Abstract

Silver nanoparticles (AgNPs) have been synthesised by many plant extracts so far. In this novel study we have synthesised AgNPs from Putranjivaceae leaf extract. The new plant Putranjivaceae was discovered in 2017 (Krishna et al., 2017) in West Bengal, India. The AgNO3 is treated with the leaf extract and subjected to microwave irradiation to get AgNPs. The nanoparticles were synthesised in just 10 minutes and subjected to characterisation for structural and morphological studies. The synthesis was rapid and shape of nanoparticles found uniform in nature by SEM and TEM analysis observed to of 20-25nm. The primary confirmation of AgNPs was done by UV-visible-spectrophotometer and EDAX. The synthesised silver nanoparticles were optimised by several parameters like pH, salinity and substrate concentration to observe the maximum production. The silver nanoparticles were then conjugated with several antibiotics for antibacterial studies out of which erythromycin showed three fold increments in its efficiency.
