The difference today is that industry knowingly appeals to nanometric ingredients, incorporating them into materials or depositing them on their surface. These nanomaterials, some of which have utterly novel properties, can be used in an extremely wide range of applications. It would be difficult to make a complete list, so disparate would it appear, but one can nevertheless cite some examples. , strengthening of plastics or concretes by incorporating nanoparticles or nanofibres. Another example is the development of materials with large surface area for absorbents or filters, antipollution surfaces, and anti-bacterial surfaces.
Scientists push forward our knowledge and understanding, and at some point a new idea for an application can spring up. A long process is then set in motion to make this application possible, starting with technical trials, then industrialisation, and finally the arrival of new products on the market. This raises the following question: To what extent did citizen or consumer decide to realise this application? The question becomes more pressing still if the negative aspects of these new products, such as suggested or proven risks, effects on the environment, the establishment of monopolies, and so on, tend to outweigh apparent benefits like efficiency, reduced cost of a service, sustainable development, and so on.
