The potential benefit of nanoscale science and engineering in our lives is clearly seen with the development of gold nanoshells. These nanostructures have promising applications in imaging and destroying cancer cells with much more finesse than current methods such as chemotherapy. The web guide looks to explain more about how nanoshells are fabricated, and how they can be used to image and target cancer. This NCLT website was created in part to serve as a guide for visitors to NISE nanomedine e...

Superabsorbent Polymer - Interactive Computational Animations on Nanomaterials
Submitted on 14-NOV-06

Superabsorbent polymers (SAP) are large chain-like molecules that can absorb water up to thousands of times their own weight. Their ability to absorb is strongly related to the surface area of the polymer that is in contact with water. The surface area depends on the polymer particles size. Fine particles result in larger area than coarse particles. ...

Many toxic chemicals can be broken down by adding titanium dioxide nanoparticles and exposing the mixture to sunlight. This animation explores this process, which is known as photocatalysis... ...

Photocatalytic Degradation of Methylene Blue by Titanium Dioxide - Interactive Computational Animations on Nanomaterials
Submitted on 14-NOV-06
Contributed by Richard Braatz, Limay Goh, Effendi Rusli, Mitsuko Fujiwara, Valerie Maynard

When titanium dioxide is illuminated with UV light, its electrons are excited to higher energy levels where they can interact with organic chemicals such as methylene blue. The interaction degrades the methylene blye molecules causing its blue color to disappear. This process is called ?photocatalysis? and has applications in medicine, energy, and environment. This animation introduces the concept of photocatalysis and step involved in the process....
