Effect of doped ZnO nanoparticles on bacterial cell morphology and biochemical composition

Emerging Trends in Nanomaterials for Antibacterial Applications

“…These NPs can be oxidized when in biological media, releasing metal ions which can generate ROS or create oxidative stress that in turn leads to biocidal effects which can range from ribosome destabilization, DNA, protein, mitochondrial, and cell wall damage to electron transport disruption and cell death (Figure 1). [47][48][49][50] Many metal ions were reported to exert toxicity against bacteria, such as Ca 2+ , Zn 2+ , Mg 2+ , Fe 2+ , Fe 3+ , Ni 2+ , and Cu 2+ , which at lower concentrations are very useful in bacterial metabolic processes but at higher concentrations become toxic to bacteria and hence have a bactericidal effect. 51 The effects of these metal ions are primarily attributed to their natural affinity for certain cellular components.…”

Challenges and opportunities for SERS in the infrared: materials and methods

“…To date, numerous studies have focused on the synthesis of doped semiconductor nanoparticles of controlled morphology with different concentration of dopant ions. 171 However, there is a huge gap between the high volume of literature on the synthesis of these materials, and the application of doped semiconductor nanomaterials for SERS detection. A recent effort to synthesize doped semiconductor nanomaterials for SERS detection was made by Wang and co-workers.…”

A Review on Synthesis and Characterization of Copper Doped Zinc Oxide Nanocomposites

“…Infections of nosocomial which is related to infection associated with health is affecting human life in significant number, as one of the leading disease of fungus, bacteria, respiratory track infection, urinary track infections, as all this segmental diseases are larger in south asia, sub African, Nigeria, as this all disease symptoms are over wheeled through bimetallic composites generally related with copper and zinc oxides [13]. Enamourous metallic oxide synthesis has been introduced, as ZnO, CuO, FeO, TiO2 etc was waving special attention for their excellent bacteriostatic and bactericidal properties in the era of nano medicine, as this synthesis modified in more enthusiastic methodology with upgrading properties in the form of bimetallic oxides largely as copper and zinc mediated nanoforms [14,15,16].…”
