Modification in Toxicity of l-Histidine-Incorporated ZnO Nanoparticles toward .

This paper presents a comparative study of the toxicity of pristine-ZnO and l-histidine-incorporated ZnO toward () as a Gram-negative model organism. Pristine-ZnO and l-histidine-incorporated ZnO with different l-histidine concentrations were synthesized using an open aqueous solution bath technique. XRD studies revealed the formation of polycrystalline wurtzite ZnO.
