P. Sunila Rani and G. Rosaiah *

ABSTRACT

Aim: To identify the anti microbial activities of silver nano particles synthesized with Rhizophora apiculata whole plant extract against the fungi and bacteria tested. Methods: In vitro anti microbial activities and characterization studies such as UV, XRD, EDX, SEM and TEM analysis were carried out for the synthesized silver nano particles. Results: The synthesized silver nanoparticles have maximum absorption at 405 nm with the average size of 3.5 nm. The XRD data showed 2θ intense values with various degrees such as 38.28°, 43.18°, 65.64° and 78.04°. SEM and TEM data showed prominent nano particle formation with a particle size of 2 nm and 21 nm respectively. Conclusions: The biosynthesis of silver nanoparticles with whole plant extract of R.apiculata provides potential source for the antimicrobial activity against bacterial and fungal diseases.
