TAILORING THE SURFACE TEXTURE OF ZNO NANO STRUCTURES: EVALUATION OF ANTIBACTERIAL ACTIVITY

Zinc Oxide nanoparticles (ZnO NPs) were synthesized by solution combustion method where here Zinc Nitrate is used in Powder format and it act as a good oxidizer and malic acid is used as fuel. In UV, the band gap was found to be around 3eV. The X-Ray Diffraction (XRD) exhibit hexagonal structure and confirmed the presences of ZnONPs (JCPDS: 36-1451).The average crystallite size is around 48 nm. FTIR spectra showed the band in the range of 400-600 cm-1, corresponds to stretching vibration mode, which confirms the presence of ZnONPs. The prepared ZnONPs are very effective for gram negative bacteria. The Gram negative bacteria comprises in their membrane structure most of which is thickness of the peptidoglycan layer
