Improved antifungal activity of zno nanoparticles biosynthesized using black cardamom

This paper demonstrates a one step, simple, and green method to synthesize Zinc oxide nanoparticles using black cardamom extract. Black cardamom extract is used as reducing agent for ZnO nanoparticles. Use of black cardamom can be justified under the light of the fact that it contains strong reducing properties. Number of characterization techniques for the analysis of synthesized material has been carried out to confirm the formation of ZnO nanoparticles. XRD pattern, UV-Vis and PL spectra explicitly confirm the formation of ZnO nanoparticles. A careful TEM investigation gives provides information about the shape and size distribution of nanoparticles. Further, antifungal activity test of these synthesized ZnO nanoparticles has been done which shows a better inhibition response for fungus.
