Abstract
― The importance of nano gold particles has been increased in the field of bio physics and medicine, recently. In this regard, the study aims to analyze how the harmless nano gold pa rticles can be transformed by respective variables. In this stu dy, electrospun PU nano-webs were impregnated with aqueous HAuCl ₄solution and UV light was irradiated on the webs. Au-ions were reduced to nano particles by photocatalytic reduction and these nano gold particles were characterized by SEM, UV-vis, Zetasiz er, Spectrophotometer, EDS. HAuCl ₄solution concentration and UV irradiation time have heen examin ed to change the amount of absorption. Nano gold particles size and UV-Vis absorbances wer e increased with HAuCl₄solution concentration and UV irradiation time.
