Resumen del Recurso
Nanotechnology
The use and control of tiny matter is called nanotechnology. The tiny matter is referred to as nanoparticles.
These particles are measured in nanometres (nm). A nanometre is one billionth of a metre (0.000 000 001m). Nanotechnology is concerned with the use an
and control of structures that are 1-100 nanometres in size.
Some of these nanoparticles occur naturally, for example in volcanic ash. Some occur by accident, for example during the combustion of fuels. Many occ
Properties of nanoparticles
Nanoparticles of a material show different properties compared to larger particles of the same material.
Use of nanoparticles
sports equipment: nanoparticles are added to materials to make them stronger whilst often being lighter. They have been used in tennis rackets,
clothing: silver nanoparticles have been added to socks. This stops them from absorbing the smell of sweaty feet as the nanoparticles have antibacteri
healthcare: nanoparticles are used in sunscreens. They offer protection and can be rubbed in so there are no white marks
Harmful effects
There are some concerns that nanoparticles may be toxic to people. They may be able to enter the brain from the bloodstream and cause harm.
Some people think more tests should take place before nanoparticles of a material are used on a wider scale.
