Currently, the development of green metal NPs through ecofriendly technique has become a major focus of researchers. The current study highlights the antimicrobial activity of Cr2O3 NPs, synthesized by Cannabis sativa (Bhang), Azadirachta indica (Neem), Ocimum sanctum (Tulsi) plants leaves extract. The characterization of Cr2O3 NPs was attained by SEM with EDX, TEM and XRD analysis. Moreover, synthesized Cr2O3 NPs were evaluated for their antimicrobial activities against fungi such as P. triticena, A. niger, A. flavous, F. species and bacteria such as S. aureus, B. subitilis, E. coli and P. fluorescence. The Cr2O3 NPs synthesized by Cannabis sativa leaves extract were found to exhibit high antimicrobial activities towards all microbial species. The Cr2O3 NPs shows a clear zone of inhibition at concentration 500 ppm. The results revealed that P. triticena was tremendously sensitive while interacting with Cr2O3 nanoparticles. The outcomes of antimicrobial studies divulged that the Cr2O3 NPs are more potent in comparison to the metal salts as well as plants leaves extract. Therefore, the Cr2O3 NPs are supposed to be great antimicrobial agents.
