Abstract

SYNTHESIZED SILVER NANOPARTICLES FROM PSEUDARTHRIA VISCIDA EXERT HIGH ANTI-MICROBIAL ACTIVITY AGAINST PATHOGENIC BACTERIA

Kunal Naik and R. Krishnamurthy*

ABSTRACT

In recent decades the use of plant based antimicrobial formulation is on increase due to microbial resistance to chemical drugs. The present study attempted to synthesize and evaluate Silver Nanoparticles (AgNPs) from methanolic extract of P. viscida under diverse temperature against pathogenic bacteria. AgNPs were prepared from a mixture of 1mM to5mM silver nitrate and 1-5% extract of P. viscida. Optimum proportion and concentration of extract and silver nitrate was determined and used for production of stable AgNPs. The characterization of stable AgNPs was done by UV-vis spectroscopy and Transmission Electron Microscope (TEM). Loss of organic content and specific characteristic of AgNPs were measured by Differential Scanning Calorimetry (DSC). The spectroscopy showed presence of AgNPs at 430 nm absorbance peak. The TEM analysis revealed AgNPs of good quality, dominant spherical in shape and particle size range from 59-95 nm. AgNPs shows similar inhibitory activity against 4 (67%) out of 6 bacteria tested. 1mM silver nitrate and 2% extract mixture prepared at 40˚c and pH 12-13 was found to be optimum for production of stable AgNPs with induced inhibitory activity that crude extract can’t gives alone. The study concludes that AgNPs of good quality, stability and antimicrobial activity can be obtained from methanolic extract of P. viscida.

Keywords: Silver Nanoparticles, Pseudarthria viscida, pathogenic bacteria, antimicrobial activity.
