“…The results obtained in this work are good and t well with the previously published ndings for similar catalysts, where comparable or even larger drops in catalyst efficiency were observed aer cycling. [55][56][57] Our results indicate that the prepared Ag-TiO 2 NPs possess high stability and durability thus opening the path, aer further studies, for a possible future industrial application.…”

“…Moreover, the dual-Z-scheme ZnO-Er 2 O 3 -Yb 2 O 3 material synthesized using co-precipitation techniques was also reported to be highly effective on S. aureus bacteria [ 75 ]. Kaur et al synthesized ZnO plates/Fe 2 O 3 rods/Ag NPs composites for the antibacterial activity of E. coli bacteria [ 73 ]. The antibacterial activity of the Ag/Fe 2 O 3 /ZnO heterostructures studied at different visible light exposure time (30, 60, and 120 min) presented good results.…”

Metal oxide nanomaterials are one of the preferences as antibacterial active materials. Due to its distinctive electronic configuration and suitable properties, ZnO is one of the novel antibacterial active materials. Nowadays, researchers are making a serious effort to improve the antibacterial activities of ZnO by forming a composite with the same/different bandgap semiconductor materials and doping of ions. Applying capping agents such as polymers and plant extract that control the morphology and size of the nanomaterials and optimizing different conditions also enhance the antibacterial activity. Forming a nanocomposite and doping reduces the electron/hole recombination, increases the surface area to volume ratio, and also improves the stability towards dissolution and corrosion. The release of antimicrobial ions, electrostatic interaction, reactive oxygen species (ROS) generations are the crucial antibacterial activity mechanism. This review also presents a detailed discussion of the antibacterial activity improvement of ZnO by forming a composite, doping, and optimizing different conditions. The morphological analysis using scanning electron microscopy, field emission-scanning electron microscopy, field-emission transmission electron microscopy, fluorescence microscopy, and confocal microscopy can confirm the antibacterial activity and also supports for developing a satisfactory mechanism.

Metal‐based nanoentities, apart from being indispensable research tools, have found extensive use in the industrial and biomedical arena. Because their biological impacts are governed by factors such as size, shape, and composition, such issues must be taken into account when these materials are incorporated into multi‐component ensembles for clinical applications. The size and shape (rods, wires, sheets, tubes, and cages) of metallic nanostructures influence cell viability by virtue of their varied geometry and physicochemical interactions with mammalian cell membranes. The anisotropic properties of nonspherical metal‐based nanoarchitectures render them exciting candidates for biomedical applications. Here, the size‐, shape‐, and composition‐dependent properties of nonspherical metal‐based nanoarchitectures are reviewed in the context of their potential applications in cancer diagnostics and therapeutics, as well as, in regenerative medicine. Strategies for the synthesis of nonspherical metal‐based nanoarchitectures and their cytotoxicity and immunological profiles are also comprehensively appraised.
