Abstract
This study describes a simple and convenient method for the preparation of polymer-stabilized colloidal gold by means of an ultra-violet (UV) irradiation technique. Methoxy polyethylene glycol (MPEG) acts as the reducing agent in the presence of the UV irradiation towards gold ions and also acts as the stabilizer of gold particles. The gradual broadening of the UV-visible spectra of the stabilized gold system reflects the formation of larger particles with a longer period of exposure to the UV radiation.
