Select Committee on Science and Technology Fifth Report


2 Background

Definitions: Micro and Nano

7. There is no strict, agreed definition of what constitutes nanotechnology and nanoscience. The terms refer to a range of technologies and processes used to manipulate matter at an extremely small length scale, usually taken to be in the range of 0.1 and 100 nanometres. (One nanometre is one billionth of a metre. Ten molecules of hydrogen side by side measure approximately one nanometre. A human hair is approximately 80,000 nanometres wide.) Broadly speaking, nanoscience refers to the study of the manipulation and assembly of matter at the atomic or molecular level, whereas nanotechnology is taken to be the application of nanoscience to create products and processes.

8. Nanotechnology is often categorised as either "top-down" or "bottom-up". Top-down nanotechnology involves the fabrication of nanoscale structures by machining processes carried out on larger structures, while bottom-up refers to the creation of organic and inorganic structures at a molecular level. At present nanotechnology is still mainly at the top-down stage. It is also, by nature, multidisciplinary: the potential applications span the sciences, medicine and engineering. The really exciting developments are expected to arise from the fusion of the engineering of increasingly small components with the biology and chemistry of assembling and manipulating structures, atom by atom.

9. Chemists are fond of saying that they have been practising nanoscience for many years.[9] This may be true, although they have not necessarily been practising it with those in adjacent disciplines. The Chief Executive of the Engineering and Physical Sciences Research Council (EPSRC) confirmed that "it is certainly true that many things that today would come under the heading of nanotechnology have been going on for a long time in some form or other without that label".[10] But it is the development of new tools capable of manipulating materials and substances at the nanoscale that has provided new scientific and commercial opportunities. As Patrick McDonald, the DTI official leading on the nanotechnology strategy, told us: "What has changed is an understanding of how we can manipulate things at molecular level. The rest of it we have been doing for a long time".[11]

10. Nanotechnology should be distinguished from microtechnology and microsystems, also referred to as microelectronic and mechanical systems or MEMS. One micrometre (or micron) is equivalent to one thousand nanometres or one thousandth of a millimetre. The application of microtechnology is generally far closer to the market and to a large extent it is already with us. It has been commercially exploited for many years, for example, in the production of ever smaller electronic devices and more powerful small computers.

11. In establishing the MNT Initiative, Lord Sainsbury was keen to point out that the DTI drew no distinction between micro and nanotechnology. He told us that "when we are talking about nano here, we are talking really about nano and micro because it really does not make any sense commercially to make a distinction between them".[12] This is an important point. The boundaries between nanotechnology and microtechnology may be blurred—there is a degree of commonality in the techniques and equipment involved in micro and nanotechnology —but they are, in essence and in application, very different. It is at the nano not the micro scale that the physical and chemical properties of materials change and the scope for revolutionary advances in technology can be realised. There is some logic in combining micro and nano in order to maximise the potential of existing facilities and to avoid problems of definition. There is also a cost. By making no distinction between micro and nanotechnology for the purposes of the MNT Network, the DTI is making no specific commitment to supporting nanotechnology itself. We explore the consequences of using this definition in Chapter 3.

Applications of nanotechnology

12. Some of the benefits of nanotechnology are already with us. Nanoparticles and nanomaterials are used in the production of certain goods, such as sunscreens, carbon nanotube based tennis rackets, burn dressings and dental fillings. Other commercial applications are expected in the near future; still more are predicted for more distant horizons. Many of these commercial applications are predicted to stem from the interaction of several different disciplines and technologies at the nanoscale. The Prime Minister has said that "this kind of disruptive technology may create whole new industries and products we can't begin to imagine".[13] In recent months, newspapers and science journals have been reporting on exciting potential applications for the future, from the precise delivery of drugs to parts of the body to cables from earth to space capable of carrying small vehicles and producing energy.[14] Several examples of applications are included in Table 1.

Early years of Government support

13. The history of UK Government support for nanotechnology is perhaps surprisingly long. It began in 1986 when the National Physical Laboratory, in conjunction with DTI, launched the National Initiative on Nanotechnology to promote awareness. This was built upon two years later when the DTI launched the LINK Nanotechnology Programme (LNP). Over the ten years of its life, the LNP provided £23.6m in support of 28 projects involving 15 universities, 19 SMEs and 25 large companies. An evaluation of this programme concluded that its impact had been high, increasing sales for participants by £8-12m, and providing, for the majority of them, technical progress, increased R&D activity and spin-off benefits.[15] Three of the companies involved went on to become market leaders in their respective microsystems sectors: anti-judder automotive braking systems, fibre optics and semiconductor fabrication systems.[16]

14. The LNP came to an end in 1998, but there was no immediate attempt to build upon its apparent success. We sought to discover why. Patrick McDonald explained that, in spite of the large number of benefits produced "we did not find a particular large industrial engagement".[17] He told us that only two companies—Unilever and GlaxoSmithKline—had shown to the DTI any active interest in nanotechnology in the early schemes.[18] The DGRC told us that in the early days much of the UK funding came from the US defence laboratories and that "we were perhaps a wee bit late coming on-stream".[19] Patrick McDonald guessed that the main reason was simply money—the DTI's funding for technological support had been declining up until 2002 and there was "very little money to spend in this technology area".[20] We have not been given a satisfactory explanation for the absence of a successor programme to the LINK Nanotechnology Programme.

15. Since the end of the LNP the DTI's non-Research Council support for nanotechnology consisted of an assortment of small scale projects that included an element of nanotechnology rather than being explicitly focussed on developing the technology itself. These included LINK programmes in applied genomics, optics and biotechnology. It was only in 2000-01 that the DTI appeared to begin thinking seriously about providing significant levels of support for nanotechnology. The Foresight materials panel produced a report on nanotechnology in 2000 which led to three nanotechnology research projects costing around £5m. Then the Research Councils established two Interdisciplinary Research Collaborations in nanotechnology and announced a basic technologies programme including support for nanotechnology based projects worth £12m.[21] The department sought to learn lessons from the progress made in other countries by sending multidisciplinary missions to the US and Germany in 2001-02.[22]

16. The failure to capitalise on this early work has proved costly. By 2001, the UK had fallen from a position generally regarded to be one of relative strength in nanotechnology research to one of relative weakness. The DTI sponsored mission to Germany and the USA concluded that "In 1986, the UK was on the threshold of opportunity; in 2001 we are on the threshold of a major challenge".[23] The independent review of the LNP reported that "There was a general feeling that the UK had fallen behind those countries that had continued to underpin the development of nanotechnology (US, Germany, Switzerland). It was also felt that the focus on nanotechnology in the UK had diminished after the support for infrastructure under the LNP was not continued".[24] The extent to which the UK has fallen behind in international terms is illustrated in Table 2. Although reliable comparable figures are not always available it is clear that the US and Japan have taken a very significant lead in investing in nanotechnology. We were interested that no-one we met on our visit to Germany complained about a lack of funding for nanotechnology. Far Eastern economies such as South Korea and Taiwan are also investing huge amounts in nanotechnology research.

17. Even with the money announced under the MNT Initiative, the UK is not competing in the same league as major international competitors and is significantly behind both France and Germany. This assessment was confirmed by the Taylor Report, which concluded that "the UK is indeed behind its major international competitors in the industrial exploitation of nanotechnology, and in the level of UK industrial support for R&D on nanotechnology applications".[25] The DTI acted with commendable foresight in engaging industry and universities in a nanotechnology programme in the 1980s when few other countries had taken such steps. But the department's failure to build upon the LNP programme with something similar represents a very damaging failure, which has contributed significantly to the UK falling from a position of international strength in nanotechnology. This lack of foresight and ambition has left the UK in the position of having to catch up.

The Taylor Report

18. When invited by the Science Minister, the DGRC assembled an impressive group of members from industry and from different academic disciplines to work on a strategy for nanotechnology in the UK. In addition to reviewing existing studies in the area the group conducted a comprehensive benchmarking study of UK nanotechnology capability in academia and industry and looked at the activities of leading competitor nations. The advisory group reported back to the Minister for Science and Innovation and the Report, New Dimensions for Manufacturing: A UK Strategy for Nanotechnology, was published in June 2002. The main findings and recommendations of the Taylor Report are summarised in Box 1.

19. To prepare its report, the advisory group commissioned a review of nanotechnology research in the UK. This review team formed the impression that the UK was not a world player in nanotechnology. It lacked "critical mass" in any one domain of the subject. Although the UK was strong across many areas the highest quality research seemed to be in electronics and molecular nanotechnology. The review suggested that if the UK wanted to compete on the international stage with a limited budget, a more focussed approach, possibly based on these two areas, might be a good strategy. The UK was found to have a good base of facilities of international standing which, given their wide geographic distribution, might benefit from a "more formalised high profile network".[26]

20. The Taylor Report recommended that companies needed to be convinced of the benefits of using nanotechnology and that steps had to be taken to guarantee both industry and academia access to appropriate facilities and to well trained staff. In order to guarantee access to the right facilities the Report recommended the establishment of at least two National Nanotechnology Fabrication Facilities where individuals and firms could fabricate and test potential products. It was argued that these centres should be focussed around particular applications rather than trying to cover too many, and that they should be able to support the incubation of new ventures.[27]

21. In addition to these main findings and recommendations the advisory group identified six key application areas (out of an initial list of 14) in which the UK has research strengths and industrial opportunities:

  • Electronics and communications;
  • Drug delivery systems;
  • Tissue engineering, medical implants and devices;
  • Nanomaterials (bio/medical/functional interface);
  • Instrumentation, tooling and metrology; and
  • Sensors and actuators.

The report set out a series of detailed targets designed to illustrate what success would look like in 2006 in each of these areas. The steps necessary to reach these targets were also outlined. The Report recommended that the Government take forward the establishment of the first two fabrication facilities "as a matter of urgency".[28]

22. In our view, the Taylor Report provided a comprehensive, ambitious, affordable and achievable strategy for the development of UK nanotechnology capability: it provided a ready made blueprint which the DTI could have taken forward and implemented in full.
