Phys. Bammidi, Synthesis and characterization of zinc oxide nanoparticles and its antimicrobial activity against Bacillus subtilis and Escherichia coli. Though ZnO shows light covalent character, it has very strong ionic bonding in the Zn–O. More emphasis should be given to the correlation between ZnO-NPs structural, optical, electrical, chemical properties, and their bacterial toxicity. 87(5), 1917–1925 (2010). Optical properties can be tuned by doping. Its applications ranged from personal care products, sensors, antibacterial creams, and biomedical applications. For instance, Padmavathy and Vijayaraghavan [12] suggested that the antibacterial action of ZnO-NPs is due to the membrane injury caused by defects such as edges and corners, which results from the abrasive surface of ZnO. J. The FESEM images (Fig. Chem. Sci. Zinc oxide (ZnO) is the most commonly used nanoparticles among different nanoparticles. 3(1), 95–101 (2007). HHS doi:10.1016/S0922-338X(98)80165-7, A.

However, some metal oxides are highly toxic, for example, Al2O3 toxicity toward many cells [8]. Limbach, A. Bruinink, W.J. Oxygen annealing stimulated a high amount of oxygen atoms to be absorbed onto ZnO surface, thereby enhanced antibacterial response inducing more ROS in the suspension resulting in intense oxidative stress towards the bacteria. Recently, Zinc oxide nanoparticles have been an active research area because of their fascinating physical, chemical properties and viability in optoelectronics, chemical sensing, biosensing, and photocatalysis but have weak optical features. Appl. While other researchers used appropriate capping agents [12] or deflocculants (sodium silicate Na2SiO3 or sodium carbonate Na2CO3). doi:10.1039/b708662h, K. Tam, A. Djurišić, C. Chan, Y. Xi, C.
