SYNTHESIS OF BLACK CARDAMOM & BLACK PEPPER MEDIATED ZINCOXIDE NANOPARTICLES AND THEIR ANTIBACTERIAL ACTIVITIES

摘要

In the present work, black cardamom (Amomum subulatum) and black pepper(Piper nigrum)extract mediated zincoxide nanoparticles have been synthesized.These nanoparticles are characterized by ultraviolet-visible spectroscopy and dynamic light scattering (DLS).The size of the synthesized zinc oxide nanoparticles found between 10-40 nm.These nanoparticles show a very good bacteriocidal influence on E.coli according to concentration of these nanoparticles used.In this work three different concentration of zinc nanoparticles were used to evaluate antibacterial activities.
