GNPs are biosynthesized which can be used as carrier molecules for drug, DNA and bio-active molecule

The recent advances for a reliable, eco-friendly, non-toxic processes for the synthesis of nanomaterials has become a prone area of nanotechnology’s researcher now a days. Despite sculpturing the synthesis of nano particles to desired characters, the application of them in biomedical field is still limited due to the presence of toxic chemicals used in their synthesis. This has motivated the research in nano particles synthesis through biological route.One of the promising method that shows a huge potential is grounded on the biosynthesis of nanoparticles using biological sources like plants, micro-organisms such as bacteria, fungi, algae and others. In this study, a non-hazardous method biosynthesis approach for the synthesis of gold nano particles (GNPs) has been investigated using marine bacteria procured from Southern Ocean particularly in Indian sector. The nanoparticles were biosynthesized by microorganism through metabolism of gold precursor auric chloride into GNPs. The GNPs produced were characterized using UV–Vis spectrophotometer, SEM, DLS and EDAX. This work on nanoparticles synthesis offers a new approach to exploit marine water and thus shifting the usual trend from soil microbes to marine bacteria and its amenability for large-scale production.
