摘要：

We have successfully synthesized ZnO nanoparticles (NPs) from solution combustion method using combustible fuel (Green gram). XRD pattern confirms that the prepared compound is composed of wurtzite hexagonal zinc-oxide. FTIR spectrum of ZnO NPs shows the band at similar to 417 cm(-1) associated with the characteristic vibration of Zn-O. The UV-Vis spectrum shows a strong absorption band at similar to 365 nm which is blue shifted due to quantum confinement erect. TEM images show the average sizes of the nanoparticles are found to be almost similar to 15-30 nm. The as-synthesized product shows good electrochemical sensing of dopamine. Furthermore the antibacterial properties of ZnO NPs were investigated by their bactericidal activity against four bacterial strains using the agar well diffusion method.
