The size and optical properties of the gold nanoparticles are investigated and the synthesised magnetite samples are surface treated to make them either oil and water soluble.
This is a directed practical for teams of three with small group demonstrator led evaluation of the properties of the prepared nanoparticles. The slides are editable and should prove a suitable resource for introducing nanotechnology. Areas highlighted are surface area/ volume(mass) ratio, optical properties and the unusual magnetic properties of magnetite nanoparticles. I have included a couple of links to YouTube videos (Morpho butterfly physical colour and geckos sticky feet which help reinforce these points. This is an on-going project and will be updated as activities are developed.
