摘要
Over past few years various protocols have been developed to produce gold nanorods by chemical synthesis but, most of the chemical used in synthesis are toxic which shows immense effect on environment. In the present investigation, we developed a simple bio-based synthesis of gold nanorods employing blue pigment produced by Streptomyces coelicolor klmp33 using microwave irradiation. The pigment used to reduce HAuCl4 in solution to yield gold nanorods with in 120 s. The gold nanorods were characterized by UV-visible spectroscopy; transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The bio-based synthesis developed in this method is safe, eco-friendly, rapid and appropriate way for bulky synthesis of gold nanorods.
