This study deals with facile and rapid synthesis of AuNPs using Justicia adhatoda and Ocimum tenuiflorum leaves extracts. The synthesized AuNPs were characterized by UV-Vis, FT-IR, AFM and TEM techniques. The phytochemical analysis showed the presence of bioactive secondary metabolites, which are involved in the synthesis of nanoparticles. The surface plasmon resonance (SPR) observed at 500-600nm, confirmed the eco-friendly synthesis of AuNPs (gold nanoparticles), respectively. The TEM images showed poly dispersed and round, oval shapes of AuNPs with an average particles size of 5-50 nm. TEM results are in close agreements with that of AFM analysis. The FT-IR spectroscopy revealed the presence of C-Br, C-Cl and NO2 groups, which involved in the synthesis of AuNPs. Thus obtained AuNPs can be a new generation of diagnostic probes, promising tools for pharmaceutical or cell biological applications.
