Comparison of anticancer activity of biocompatible ZnO nanoparticles prepared by solution combustion synthesis using aqueous leaf extracts of Abutilon indicum, Melia azedarach and Indigofera tinctoria as biofuels.

Recently, there has been an upsurge in the use of naturally available fuels for solution combustion synthesis (SCS) of nanoparticles. Although many reports suggest that these biofuels pose less harm to the environment, their strategic advantages and reliability for making NPs has not been discussed. In the present work, we try to address this issue using plant extracts as biofuels for the SCS of zinc oxide nanoparticles as a model system.

ZnO nanopellets have selective anticancer activity.

This research work presents the synthesis of ZnO nanopellets (ZNPs) by low temperature hydrothermal approach and evaluation of their antibacterial activity, cytotoxicity in vitro and in vivo. Structural and morphological studies conducted on the sample reveal hexagonal ZNPs in the size range of 250-500 nm. Surface area measurements showed high porosity of the sample compared to conventional ZnO nanoparticles.
