RIS Discussion Papers Nanotechnology Development in India An Overview Amit Kumar Discussion Paper 193Nanotechnology Development in India: An Overview Amit Kumar Abstract: Nanotechnology has been heralded as a revolutionary technology by many scholars worldwide. Being an enabling technology, it has the potential to open up new vistas in the field of R&D in various multiple disciplines and have wide domain of sectoral applications, ranging from healthcare/medicines, electronics, textiles, agriculture, construction, water treatment, and food processing to cosmetics. Much of these applications are very much pertinent for a developing country like India. In this context, the government has been playing a pioneering role in fostering and promoting nanotechnology R&D in India since early 2000s. This discussion paper attempts to capture the nanotechnology development in India by highlighting the various initiatives undertaken by the government to promote basic R&D in it, the major actors involved and the state of regulatory framework existing in the country. It also looks into these aspects vis-à-vis certain global initiatives/trends. Keywords: Nanotechnology, nanomission, risk and regulation, capacity building, environmental and health impacts 1. Introduction: Nanotechnology and Its Implications Nanotechnology is a multidisciplinary as well as an interdisciplinary area of inquiry and application. The broad spectrum of applications that nanotechnology is and will be catering to speaks of its omnipresence. Be it in agriculture, energy, electronics, medicine, healthcare, textiles, transport, construction, cosmetics, water treatment etc., nanotechnology finds a role to play or rather a ‘defining role’ to play, as suggested by many scholars worldwide. Research Associate, RIS. Email: This study is part of a wider RIS work programme on Science, Technology and Innovation. RIS undertook research on implications of nanotechnology, synthetic biology and food technologies as part of the Global Ethics in S&T Project (2011-2014) which had support from the European Commission’s Seventh Framework Programme (FP/2007-2013) through EC Grant Agreement 266592. 1The ideas and concepts behind nanoscience and nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology on 29 December 1959 (Fenyman 1960), long before the term nanotechnology was used. In his talk, Feynman described a process in which scientists would be able to manipulate and control individual atoms and molecules. Over a decade later, in his explorations of ultra precision machining, Prof. Norio Taniguchi coined the term nanotechnology (Taniguchi 1974). It wasn’t until 1981, with the development of the scanning tunneling microscope that could aid in viewing individual atoms that modern nanotechnology began. Eric Drexler expanded Taniguchi’s definition and popularised nanotechnology in his book Engines of Creation: The Coming Era of Nanotechnology (Drexler 1986). Nanoscience is the study of phenomena and manipulation of materials at atomic, molecular and macromolecular scales, in order to understand and exploit properties that differ significantly from those on a larger scale. Nanotechnologies are the design, characterisation, production and application of structures, devices and systems by controlling shape and size on a nanometer scale. At this scale, the general physical, chemical, electrical, biological and optical properties of a material start behaving in a unique and peculiar way. This uniqueness and peculiarity opens up new vistas for enquiry and applications. In technical terms, nanotechnology has been defined by many scholars and organisations worldwide (see Table 1). Nanotechnology, being an enabling technology of emerging techno-economic paradigm, is still in the nascent phase of its research, development and innovation. Considering the new and distinct features of nanotechnology, many researchers, scientists and academicians propose that it is a new emerging disruptive technology, 1 which is quite different from sustaining technologies. A technology is considered disruptive when its utilisation generates products with 3 Table 1: Definitions of Nanotechnology Source Definition US: National Nanotechnology is the understanding and control of matter at dimensions of roughly 1 Nanotechnology to 100 nanometers, where unique phenomena enable novel applications.

Moore (1991) adds clarity to this aspect of disruptive technologies by noting the generation of discontinuous innovations that require users/adopters to significantly change their behaviour to use the innovation. Tushman and Rosenkopf (1992), Anderson and Tushman (1990), and Kassicieh et al. (2002) state that disruptive technologies are scientific discoveries that change the usual product/technology paradigms and provide a basis for a new more competitive one. Walsh and Linton (2000) argue that disruptive technologies can either be a new combination of existing technologies or new technologies whose applications to problem areas or new commercialisation challenges can cause major technology product paradigm shifts or create entirely new ones. The point to draw from here is that in case of nanotechnology, both innovation and innovation framework takes a change-over. In the first years of the new millennium, governments around the world created national nanotechnology programmes that spent billions of dollars (Roco 2003), reconfigured institutional arrangements, and constructed new sites for research and development. Many of these actors present nanotechnology as an enabling platform for other transformative innovations that will become even more powerful through its convergence with biotechnology, information technology, and cognitive science. A number of observers have catalogued societal issues that emerging nanotechnologies may raise. The early treatment by Roco and Bainbridge (2001), for example, includes implications of economic, political, educational, medical, environmental, and national security import, as well as potential consequences for privacy and global equity (the “nanodivide”). Moore (2002) divides the implications of nanotechnology into three categories: social, including environmental, health, economic, and educational; ethical, including academic-industry relations, abuse of technology, social divides, and concepts of life; and legal, including concepts of property, intellectual property, privacy, and regulation. 52. Global Trends Worldwide governments have launced many nanotechnology- specific initiatives/programmes to leverage the potentialities of nanotechnology for social and economic gains. In 2005 itself, more than 62 countries launched national nanotechnology-specific activities world over (Maclurcan 2005). The research and development (R&D) effort was significantly promoted world over with the announcement of the National Nanotechnology Initiative (NNI) in the 2001 by the USA. Most advanced countries have based their own programmes on the groundwork laid by the NNI. The NNI is the most comprehensive R&D programme in nanoscience and technology in the world. The focus of NNI is on research and development of nanoscale science and technology for economic benefit and national security. Its programmes are aligned with the goals of the participating agencies. It has got a flexible R&D infrastructure which consists of centers, networks and user facilities as well as companies with nanotechnology products. In case of Europe, most countries have government-supported major nanotechnology research and development (R&D) initiatives. China has invested in nanotechnology through its medium and long term programmes. The National Enabling Technologies Strategy (NETS) was launched by the Australian Government to provide a structure for the responsible development of enabling technologies such as nanotechnology and other new technologies as they emerge in Australia. In 2003, Taiwan launched its National Science and Technology Programme for Nanoscience and Nanotechnology. Taiwan has also developed Nano Mark which is the world’s first government-established system for certifying nano-products. The government spending on nanotechnology in Republic of Korea has increased by a considerable amount as compared to previous years. Its NNI mainly focuses on improving Korea’s position in the world in certain competitive areas. Nanotechnology in Japan is largely financed by government agencies and large corporations. It 6is a leading country in areas like nanomaterials, nanoelectronics, and nano-bio-devices. In Singapore, the nanotechnology funding is done through Agency for Science, Technology and Research that was started in September 2001 with a goal of beginning nanotechnology research as part of Singapore’s effort to build on accumulated capabilities and the promotion of innovations in areas that fuel Singapore industries. Canada’s nanotechnology activities mainly move around regional networks and the National Institute for Nanotechnology (NINT). Globally, governments currently spend about US 10 billion per year on nanotechnology research and development. By the end of 2011, the total government funding for nanotechnology research worldwide was more than US 65 billion, which is expected to rise to US 100 billion by 2014. When figures for industry research and various other forms of private funding are taken into account, which were thought to have surpassed government funding figures as far back as 2004, it is estimated that nearly a quarter of a trillion dollars will have been invested into nanotechnology by 2015 (Cientifica 2011). In terms of patenting, according to studies carried out by Statnano (2013), 27,350 patents had been published by the end of 2012 in United States Patent and Trademark Office (USPTO), among which 57 per cent were published by the US, giving the first rank to this country while Japan, Republic of Korea, Taiwan and Germany held th the next ranks. India ranked 18 with 117 published patents at USPTO. In the same period, more than 13,350 nanotechnology patents were granted, which equaled 5.7 per cent of the total patents in the same year. In this ranking also, the US ranked first, followed by Japan, Republic of Korea, Taiwan and Germany. In terms of publications, Centre for Knowledge Management of Nanosciemce and Technology’s (CKMNT) analysis revealed that 7the top 10 countries in nano S&T publications for the year 2012 were China, USA, South Korea, India, Germany, Japan, France, Iran, UK and Spain. During the past three years, China has surpassed US in these publications and has become the single largest contributor of scientific publications worldwide in the nano science and technology (Nanotechnology Now 2013). As far as nanotechnology market effect is concerned, a recent research study, “Nanotechnology Market Outlook 2017” by RNCOS, a business consulting service firm, has identified that the global nanotechnology industry has been growing at a rapid pace with rising applications in sectors like drug delivery, diagnostic devices etc. In addition, market trends like nanotechnology based thin film solar cells with high efficiency, nanomaterials with higher strength, robust growth in nanofibers and nanomedicine market, etc., are booming growth in this industry. Considering the above factors, the global nanotechnology market is anticipated to grow at a CAGR of around 19 per cent during 2013-2017 (RNCOS 2013). The nanotechnology market prospects, as envisaged by various market research bodies, are forecasted to be very positive; Lux Research, National Science Foundation (NSF) and Cientifica projected these to be around a trillion dollar business by 2015. 3. Importance for Developing Countries As, there are many wider applications of nanotechnology, experts have reckoned a list of top ten nanotechnology application areas which are of concern for developing countries such as India with respect to addressing UN Millennium Development Goals (MDGs) goals (Table 2). 8Table 2: Applications of Nanotechnology with Examples Sl.

Apart from the applications mentioned in Table 2, nanotechnology is being used in textiles, ICT, cosmetics and personal care products, electronics and home appliances, defence, etc., all across the world. All these applications of nanotechnology can be leveraged for social and economic development of the developing countries such as India. 4. Evolution of Nanotechnology in India th The 9 Five-Year Plan (1998-2002) had mentioned for the first time that national facilities and core groups were set up to promote research in frontier areas of S&T which included superconductivity, robotics, neurosciences and carbon and nano materials. Planning Commission supported number of such R&D programmes under basic research (GOI 1998). 11However, the thrust came with the launch of “Programme on Nanomaterials: Science and Devices” in 2000 by the Department of Science and Technology (DST). DST launched special initiative to generate and support some end-to-end projects leading to tangible processes, products and technologies after realising the importance of nanomaterials and their far-reaching impact on technology (DST 2001). In 2001-2002, the DST set up an Expert Group on “Nanomaterials: Science and Devices”. The Government identified the need to initiate a Nanomaterials Science and Technology Mission (NSTM) in the th 10 Five Year Plan (2002-07) after taking into consideration the developments in nanotechnology. A strategy paper was evolved for supporting on a long-term basis both basic research and application oriented programmes in nanomaterials (DST 2001). The Tenth Five Year Plan (2002-2007) document identified various areas for mission mode programmes such as technology for bamboo products, drugs and pharmaceutical research, instrument development including development of machinery and equipment, seismology, and also nano science and technology (GOI 2002). Subsequently, the National Nanoscience and Nanotechnology Initiative (NSTI) was launched in October, 2001 under the aegis of the Department of Science and Technology of the Ministry of Science. The motive of launching NSTI in 2001 was to create research infrastructure and promote basic research in nanoscience and nanotechnology. It focused on various issues relating to infrastructure development, basic research and application oriented programmes in nanomaterial including drugs/drug delivery/gene targeting and DNA chips. Nanotechnology was heralded as a revolutionary technology with applications in almost every aspect of life. Overwhelmed by the promising prospects of nanotechnology applications and in order to further enhance the visibility of India 12in nano science and technology, a Nano Science and Technology Mission (NSTM) was envisioned to give desired thrust to research and technology development in this area (DST 2006). The Eleventh Five-Year Plan (2007-2012) categorically mentioned projects to create high value and large impact on socio-economic delivery involving nano material and nano devices in health and disease. The generous Eleventh Five Year Plan Budget allocation of Rs. 1000 crore was earmarked for the Nano Mission when it was launched in 2007 (GOI, 2007). Accordingly, on 3 May 2007, a Mission on Nano Science and Technology (Nano Mission) was launched by the DST to foster, promote and develop all aspects of nanoscience and nanotechnology which have the potential to benefit the country. The Mission is steered by a Nano Mission Council (NMC) under the Chairmanship of Prof. CNR Rao. The technical programmes of the Nano Mission are also being guided by two advisory groups, viz. the Nano Science Advisory Group (NSAG) and the Nano Applications and Technology Advisory Group (NATAG). The primary objectives of the Nano-Mission are: l Infrastructure Development for Nano Science and Technology Research l Public Private Partnerships and Nano Applications and Technology Development Centres l Human Resource Development l International Collaborations l Academia-Industry partnerships to be nurtured under these programmes (DST 2008). In the Twelfth Five Year Plan (2012-2017) too, the government gave its approval for continuation of the Mission on Nano Science and Technology (Nano Mission) in its Phase-II at a total cost of Rs. 650 crore. The Nano Mission, in this new phase, would make greater effort to promote application-oriented R&D so that some 13useful products, processes and technologies also emerge. It will continue to be anchored in the Department of Science and Technology and steered by a Nano Mission Council chaired by an eminent scientist (PIB 2014). 5. Nanotechnology Research, Development and Innovation in India: Major Actors The government has played a pioneering role in promoting nanotechnology R&D in India. It has taken many initiatives to foster and promote R&D in India through several of its departments. Many schemes/programmes have been launched for infrastructure and human resource development. The government has also undertaken manybilateral/multilateral/regional initiatives with many countries to promote nanotechnology research, development and innovation (RDI). It has also encouraged PPP model to encourage nano-based product development. The main departments which have been involved in nanotechnology RDI in India are discussed below. Department of Science and Technology (DST): DST is the nodal agency in the Indian nanotechnology innovation system. It has since 1980s launched may programmes/schemes to foster R&D on miniature-scale and on nano-scale. Some such major programmes/ schemes are as follows: l Intensification of Research in High Priority Areas (IRHPAS): a programme launched by the DST during the sixth Five Year Plan (1980-1985). l The committee on Emerging Technologies was set up in 1997 to fund research for three years. Science and Engineering Research Council (SERC) also initiated a programme on nanocrystalline material. l The National Programme on Smart Materials (NPSM), which is a five year programme funded for Rs. 90 crore, was launched jointly by the five government departments, viz. Defence Research and Development Organisation (DRDO), Council of Scientific and Industrial Research (CSIR), Department of Space 14DOS, DST and Ministry of Information Technology (MIT) in the year 2000. l Nano Science and Technology Initiative (NSTI), launched by the DST, in 2001, focused on various issues relating to infrastructure development, basic research and application oriented programmes in nanomaterial including drugs/drug delivery/gene targeting and DNA chips. It gave way to Nano Mission in 2007. l The Nano Science and Technology Mission (NSTM) – an umbrella programme – was launched in the year 2007 to promote R&D in this emerging area of research in a comprehensive fashion. An allocation of Rs. 1000 crore for five years was made. The main objectives of the Nano Mission are: basic research promotion, infrastructure development for carrying out front- ranking research, development of nano technologies and their applications, human resource development and international collaborations. Through the NSTI and later Nano Mission, the DST has sponsored many nanoscience and nanotechnology projects across the country in various universities and research centres/laboratories. However, on analysing the budget of DST in the period 2001-2013, it is found that theDST has invested around Rs. 965 crore in the Nano Mission since its inception in 2007. The year-wise allocations are shown in Figure 1. From Figure 1, it can be easily made out that over a period of time the budget allocation for the Nano Mission has decreased considerably. In fact, it is now half of what it was at the time of its inception in 2007. This is a disturbing trend as far as development of an effective Indian nanotechnology innovation system is concerned. The study finds that the share of Nano Mission’s budget in the total DST’s budget has declined from around 10 per cent in 2007 to just 3 per cent in 2013. At this juncture, it would be appropriate to give a comparative figure of the US Nano R&D funding during 2002-2013, which is 15far more than what the Indian government has invested. The US government had allocated US 16.9 billion during financial years 2002-2013 for nano R&D (Bangalore India Nano 2013). For developing physical infrastructure, the DST has established Units on Nano Science, Centres for Nanotechnology, Centre of Computational Materials Science and Thematic Units of Excellence on Computational Material Science in various universities and government research centres/laboratories across the country. As far as human resource development is concerned, the Nano Mission has launched PG programmes (M.Sc and M.Tech in Nanoscience and Nanotechnology) at various universities and colleges all across India and till 2012-13, 17 such courses were being run by it in the country. Figure 1: DST Nano Mission Funding in the Period 2006-2013 Source: DST Budget Documents (analysed by author). 16For nurturing the Public-Private-Partnership (PPP) activities, the DST had sanctioned a few nanotechnology projects (DST 2008). The notable among them are: l Nano Functional Materials Technology Centre (NFMTC) at the Institute of Technology Madras, Chennai: The Centre is working on cost effective method for the production of oxide ceramic powders of nano size; consolidation and sintering of nanocrystalline oxide powders for the production of bulk ceramics; nanocrystalline diamond (NCD) films/coatings on die-inserts and plugs to increase wear-resistance and durability; cost effective production of large scale and highly pure random and aligned carbon nanotubes (CNT); and nanostructured multi- drug-delivery system for hard tissue applications and CNTs for laser based treatment of cancer by photodynamic therapy. The participating industries are Murugappa Chettiar Group and Orchid Chemicals and Pharmaceuticals. l Development of high performance rubber nanocomposites for tyre engineering: This project being implemented at Mahatma Gandhi University, Kottayam envisages the development of novel technologies in tyre engineering band on nanosize fillers in collaboration with Apollo Tyres. l Research programme on Smart and Innovative Textiles (SMITA) at the Indian Institute of Technology, Delhi: Smart textile is an emerging area. The programme aims at fundamental understanding of generation of novel materials such as nanofibres, nanofinishes, and encapsulated phase change materials with desired characteristics; investigation of novel methods that are suitable for integrating above materials to textile substrates; fundamental understanding of the effect of the above materials and methods on functionalisation of textile structures for developing smart textile; development of technology for upscaling the above processes for industrial benefit and creating new products for high value addition in the textile sector and creating comprehensive expertise and competence within the country by man-power training and enhancement of technical knowledge base. The participating industries are Resil 17Chemicals, Bangalore; Purolator India Limited, Gurgaon; and Pluss Polymers Private Limited, Delhi. l Support to Nanotechnology Business Incubator (NBI) at NCL: The NBI has nurtured activities by seven start-up companies on items like – computational modelling of flow and chemical processes, therapeutic potential of biotechnologically engineered antibodies, ocular and maxillofacial implants, and 12 start-up companies are under incubation presently as Resident Incubates on items like maxillo-facial surgery, organic chemical synthesis, etc., (DST 2013). As far as the international collaborations in the field on nanoscience and nanotechnology research, development and innovation are concerned, the DST has launched bilateral joint- research projects with more than 25 countries and multilateral research projects with regional/multilateral bodies such as EU, BRICS and IBSA. The DST has been actively promoting international collaborations through bilateral joint research-projects over a period of time. The investment made by DST has remarkably increased almost 10 times in the period 2006-2012 (Figure 2). Figure 2: DST Investments on International R&D Collaborations in Nanotechnology Source: Author’s own analysis. 18It is also seen that the number of international joint-research projects on nanoscience and nanotechnology increased almost three times in the same period 2006-2012 (Figure 3). Figure 3: DST Sanctioned International Projects on Nanoscience and Nanotechnology Source: Author’s own analysis. These international collaborative projects cover a range of nanoscience and nanotechnology basic and applied research in areas having diverse applications such as: l Healthcare/medicine/drug delivery l Sensors l Energy storage in batteries l Solar energy l Fuel cells l Other areas of use of nano-materials such as thin films, carbon nanotubes, nano composites, etc. 19
