Abstract

The present study reports facile phytomediated synthesis of ZnO nanoparticles (ZnO NPs) using hydrothermal combustion from Croton bonplandianum Bail. The characterization studies revealed that an average 44 nm size spherical ZnO NPs with high zinc composition having good crystalline nature. FTIR analysis confirmed the presence of functional groups O-H, sp3 C-H bend, and alkoxy C-O functional groups which might be involved in capping and reduction for ZnO NPs synthesis. The biosynthesized ZnO NPs exhibited potent antibacterial activity against Gram-positive and Gram-negative bacteria. The MIC results revealed that ZnO NPs were most effective against Bacillus cereus whereas least sensitive towards Pseudomonas aeruginosa and Vibrio parahaemolyticus. This investigation suggests that biosynthesized ZnO NPs are promising agents for antibacterial and antioxidant applications in the biomedical field.
