Abstract

One pot simultaneous reduction of AgNO3 and hydrolysis of Ti (IV) isopropoxide form coreshell type Ag@TiO2 nanoparticles. The following are their notable characteristics: electronic absorption, XRD, FTIR, TGA, DSC and HR-TEM techniques. XRD patterns reveal that anatase form of TiO2 and the noble metal (Ag) are present in them. That there is below 50nm is understood through high resolution transmission electron microscopic measurements. Agar diffusion method examined the antifungal properties of Ag@TiO2 core-shell nanoparticles against Candida Albicans, Candida Glabrata, Aspergillus Niger and Aspergillus Flavus. The Ag@TiO2 core-shell nanoparticles show enhanced antifungal activity. These factors give the idea that TiO2, if supported on the exterior of the Ag NPs without aggregation is confirmed to be an efficient novel antifungal agent.
