Anitha Rajasekaran*, Pramiya Nataraj, Manimozhi Ranganathan, Priyom Bose
ABSTRACT
Plumbago capensis root extract can be effectively used in synthesis of
silver nanoparticles. The minimum concentration of the extract
required to synthesis was 100μl. The silver nanos so synthesized had a
maximum absorption of 419nm at UV-VIS spectroscopy and FT-IR
analysis indicates capping of the silver nanoparticles. The Scanning
and Transmission electron microscopy revealed spherical to oblong
shaped particles of 18.69 nm to 46.71nm in length. Curvularia lunata
and Aspergillus fumigatus was inhibited by 100% at 1000 μg/ml silver
nanoparticles. The MIC value for C. lunata was 300μg/ml and A. fumigatus was between
750-1000 μg/ml respectively.
Keywords: Silver nanoparticles, Plumbago capensis root extract, Antifungal activity.
