There are worldwide more than 500 products on the market in which nanomaterials are processed. Some examples are solar cream with the nano particles titaniumdioxide and nano particles of silver in washing machines and clothes in order to kill bacterias. Nano materials occur also in diverse products such as tennis balls and rackets, packing materials and cosmetics. Tennis rackets become stronger and packing materials become ‘intelligent’: it shows who made the product and indicates what has happened with it on the road from producer to client. With nano particles cosmetic materials can penetrate the skin deeper. (Look at the site nanotechproject for a complete overview) The next ten years big breakthroughs are expected in the field of health care, nutrition and industry. Some examples are: -controlled drug delivery -nanotechnology for intelligent products -nanotechnology in water treatment -nanotechnology in development and storage of sustainable energy -nanotechnology for new inplants Such applications can result in health care, electronics, environmental technology and other industries. They evoke all sorts of ethical and political questions that need to be given a moment’s thought. Questions about privacy, desirability of improvement of the human body, risks for mankind and environment and a fair society. Underneath we discuss three applications. More information about possible applications of nanotechnology can among others be found at Rathenau and Nanoned.
More than one third of the world population (2,5 billion people) don’t have the disposal ofsafe drinking-water. Besides that both developing and industrical countries struggle with huge shortages of drinking- water, proces and irrigation water for agriculture. Nanotechnology can overcome those shortages by converting (polluted) surface water, sea water and waste water into water of desirable quality. Read more...
With the introduction of nanotechnology expectations are that products like mobile phones, clothing, cars and security cameras are made cleverer and cleverer in the sense that they can react on changes in the environment or in the state of mind of the user. Read more...
A longer and better life is an important stimulus for the development of techniques that replace for example worn-out or broken parts of the body, that compensate functional restraints and that slow down, stop or even turn back the aging proces. Nanomaterials and techniques play an important role in the development of implants that support or replace body parts. Read more... .
