Abstract : The silver nanoparticles preparation following green pathways have shown great potential with wide applications in different fields include biosensing, biomedical, electronics, catalysis etc. The current study deals with the selective colorimetric detection of mercury using green synthesized AgNPs. Silver nanoparticles were prepared using the extract of Cynodon dactylon, a common medicinal plant from South India following green pathway. The fresh bio- synthesized particles were turned to colorless, together with the extension and blue shifting of Surface Plasmon Resonance band by the addition of mercuric ions into the medium and hence flagged way towards the naked eye detection of mercury and henceforth headed towards the development of cost effective colorimetric sensors. In addition, the antimicrobial potential of the Cynodon based silver nanoparticles were exploited. This work presents a unique method for the synthesis of nanoparticles from a common medicinal plant in Kerala following green approach. Furthermore, the study attempts towards the chemo sensor development for the detection of mercury, a toxic heavy metal in a cost effective manner.
