Abstract
Biomacromolecules like proteins have got much attention due to their ability to synthesize nanomaterials. A very simple and one step method of growing nanocrystals on BSA protein thin films is explored by using UV-Vis and photoluminescence spectroscopy, X-ray diffraction (XRD) and atomic force microscopy (AFM). It is observed that if different interaction times are provided between BSA thin films and HAuCl4 aqueous solutions of mM concentration, then different nanocrystals form on BSA thin films, however, they are poly dispersed in nature. The formation of gold nanocrystals is confirmed by the presence of UV-Vis absorption peak at ≈ 525 nm and the corresponding plasmonic emission is also observed. XRD analysis shows the formation of gold nanocrystals having fcc structure with preferred growth in (111) crystal plane direction. Surface morphologies of the prepared thin films are investigated through AFM and it is observed that more nanocrystals are formed where more interaction time is provided between BSA and HAuCl4 aqueous solution. Langmuir-like exponential growth behavior is identified for such nanocrystals formation.
