Its microcrystals are very efficient light absorbers in the UVA and UVB region of spectra due to wide bandgap. However, the toxicity of zinc oxide nanoparticles depends on the uptake and their subsequent interaction with target cells. The compositional analysis of ZnO nanostructures by energy-dispersive X-ray analysis revealed their chemical purity. The impact of nanoparticles on the growth of bacteria and viruses largely depends on particle size, shape, concentration, agglomeration, colloidal formulation, and pH of the media [106,107,108]. microcantilever within two different detection mode : the detection of mass variation of the sensor because of the sorption of species in sensitive coating ; and the detection of the change of physical properties of the fluid. © 2003 American Institute of Physics. If it is correct, then large amounts of metal nanoparticles are required so that the bacterial cells are completely enveloped and shielded from its environment leaving no chance for nutrition to be absorbed to continue life process. a TEM images of untreated normal Salmonella typhimurium cells. Mechanism of interaction of zinc oxide nanoparticles with bacterial cells has been outlined below [120].
