Synthesis of Gold Nanoparticles: Steps Towards Paper based Aptamer Conjugated Gold Nanoparticle Bioassay

Abstract

Gold nanoparticles were synthesized by three different reducing agents: Sodium borohydride, Tannic Acid and Ascorbic acid to study the synthesis efficiency. They were characterized using different parameters and protocols like UV spectroscopy, DLS, SEM. Further, it was studied that it could be patterned on DNA and the aggregates could be used in bioassay, pathogen detection and drug delivery.
