Comparative in situ ROS mediated killing of bacteria with bulk analogue, Eucalyptus leaf extract (ELE)-capped and bare surface copper oxide nanoparticles

Green Synthesized Phytochemically (Zingiber officinale and Allium sativum) Reduced Nickel Oxide Nanoparticles Confirmed Bactericidal and Catalytic Potential

“…The difference in oxidative stress tolerance depends upon various factors as surface area, morphology, and particle size of synthesized nanomaterial playing inferential role in antibacterial action potential [29,36]. An electrostatic interaction between bacterial strains and nano-scaled materials results generation of reactive oxygen species found responsible for bacterial cell death [2][3][4][5]22] [39].…”

Facile In-Situ Fabrication of a Ternary ZnO/TiO2/Ag Nanocomposite for Enhanced Bactericidal and Biocompatibility Properties

“…On the contrary, the untreated control bacteria green fluorescent signal was not detected, showing that the cells were unaffected. A previous study reported that excessive production of ROS potentially alters the metabolic activity by damaging nucleic acids, protein synthesis and disintegrate the cell membrane [ 38 ]. The incorporation of ZnO and TiO 2 to the Ag could generate a high amount of hydrogen peroxide and hydroxyl radicals, which are destructive to the bacteria [ 39 ].…”

Biofabricated Fatty Acids-Capped Silver Nanoparticles as Potential Antibacterial, Antifungal, Antibiofilm and Anticancer Agents

“…The growing pursuits in metal-based nanomaterials synthesis are hotly debated in several fields while acknowledging their unique physico-chemical and biomedical properties with specific advocacy for fitness in clinical settings as fascinating treatment modality, worldwide [1]. Considering that there is a wide scope to achieve desired properties in synthesized nanoparticles (NPs) including shape, size and stability by manipulating reaction conditions such as pH, temperature, concentration of metal precursors and concentration and nature of bio-reducing agents [2][3][4][5][6][7][8]. Besides, surface capping or encapsulation material of NPs deserves special importance due to being directly or indirectly concerned with limiting toxicity and cations release, affinities towards miscellaneous components of immediate environment, and cells surface, enhanced dispersity and prolonged stability and enhanced internalization propensity in several cells [5,9].…”

Owing to feasibility and proven antimicrobial properties, silver NPs (AgNPs) can be argued for being the most commonly synthesized and investigated nanostructure within metallic nanomaterial's landscape, however, still yet holds consistent attention of researchers.…”
