nanoparticles are too .... to be seen even with the most powerful light .....
nanoparticles include ...... . these are molecules of .... , shaped like .... balls or ... tubes. the carbon atoms are arranged in ..... rings . different fullerenes contain ...... ...... of carbon atoms
a nanoparticle has very .... ... from the bul chemical that it's made from , for example fullerenes have very different ...... from big lumps of ......
fullerenes can be joined together to form ...... -
nanotubes - teeny tiny hollow carbon tubes , a few nanometres across
many covalent bonds make carbon nanotubes .... ... . they can be used to reinforce .... in ..... ...
fullerenes can be used in many ways they can :
1) be used in nanomedicine . the idea is that tiny fullerenes are absorbed more easily by the body than most particles . this means they could deliver drugs right into the cells where they are needed
2) be used to make lubricant coatings . these coating reduce friction a bit like ball bearings and could be used in all sorts of places from artificial joints to gears
3) be used to form nanoparticles
nanotubes can be used in many ways they can :
1) be used to make stonger , lighter building materials
2) be used in tiny electric circuits for computor chips as they are able to conduct electricity
nanoparticles can be used in many , they can :
1) be used to make sensors that detect one type of molecule and nothing else
2) be used in cosmetics such as sun tan cream and deodrant , the small particles do thier job but dont leave white marks on the skin
3) be used to help make new industrial catalyst because they have a huge surface area to volume ratio
