Studies Of Copper Nanoparticles Effects On Micro-organisms
Macroscale, gold is an inert element, meaning it does not react with many chemicals, whereas at the nanoscale, gold nanoparticles become extremely reactive and can be used as catalysts to speed up reactions. As the gold nanoparticle size decreases and the surface area to volume ratio increases, the likelihood of ferromagnetism increases. ... Read Here

Self-assembled Monolayer - Wikipedia
Thiols are frequently used on noble metal substrates because of the strong affinity of sulfur for these metals. The sulfur gold interaction is semi-covalent and has a strength of approximately 45kcal/mol. In addition, gold is an inert and biocompatible material that is easy to acquire. ... Read Article
Gold Nanoparticles For Cancer Treatment
Nanoparticles in the treatment of cancer is a promising, relatively recent development in this eld. At present, gold is a favoured material for this purpose. Formed into spheres, shells, cages or wires on the scale of ten to one thousand nanometres, gold can be bound to a wide variety of biochemically functional groups and made to ... Get Doc
Learning Activity Series - The Nano-CEMMS Center
Nanoparticles of silver are 20-50 nm and gold nanoparticles are about 13 nm. Gold and silver nanoparticles are smaller then the wavelength of light. The color they display is a result of the interaction of light with the surface of the nanoparticles; this interaction is called Plasmon resonance. ... Retrieve Full Source
