|Title:||Effect of stabilizer on preparation of silver and gold nanoparticle using grinding method|
|Keywords:||Biochemistry, Genetics and Molecular Biology|
Physics and Astronomy
|Abstract:||Silver and gold nanoparticles were prepared by grinding method using stabilizers such as de-ionized water, ethylene glycol (EG) and 5 wt% polyvinyl alcohol (PVA). From the observation, it was found that the solution's color of silver particle changed from clear color to light yellow or brown and that of gold particle changed from yellow to light blue. This indicated that the size of silver and gold particle was reduced. In addition, the optical properties of silver and gold nanoparticles were studied by UV-vis spectroscopy. It was found that the absorbance and transmission spectra of silver and gold nanoparticles depended on the type of stabilizing agent and grinding time. In addition, the observed color of nanoparticles could be explained using Maxwell triangle and in agreement with the color observed by naked eyes.|
