New Materials for Modification of Metallic Gold Nanoparticles

Nanotechnology is a field of science that deals with the studying and controlling of matter on an atomic and molecular level. It generally consists of processes such as separation, consolidation and deformation of materials by one atom or molecule to achieve a specific product with certain desirable properties. When gold nanoparticles are coated with metal complexes, it enhances its uses and applications. Gold nanoparticles are very good at absorbing and scattering light and hence have great optical properties. Various research studies conducted on gold nanoparticles have shown that these particles can successfully be used to detect cancer cells. One of these studies reported that, gold nanoparticles have a 600 percent affinity for cancerous cells. These particles are also used as catalyst in many N N O s NH O Compound A (Disulfide) chemical reactions such as in the making of plastics. Great interest has been shown in the study and development of these particles and how they can be used to improve science and medicine. In our ongoing research, our approach has been to bind metal chelating organic molecules to the gold surfaces to chemically alter the behavior of the particles. Synthesis of compound A is our initial target because the disulfide bond can be broken to form Au-S which will give it desirable characteristics in many applications such as breast cancer research. Upon completion of the synthesis of compound A, an attempt would be made to bind it to the surface of gold nanoparticles
