This review is about how antibacterial ZnONPs are. The scope encompasses testing methodologies, the impact of ultraviolet lighting, factors about ZnO particles such as size, concentration, shape, and defects, modifications to particle surfaces, and the determination of minimal inhibitory concentrations. The review concentrates on the formation of reactive oxygen species (ROS) such hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>), hydroxyl radicals (OH<sup>-</sup>), and peroxide (O<sub>2</sub><sup>–2</sup>), with an emphasis on bactericidal and bacteriostatic processes. ROS substantially affects a wide range of processes, including the consumption of harmful zinc ions in solution, the enhancement of membrane permeability, and the absorption of NPs and cell walls. This ultimately prevents cell growth and triggers cell death by reducing mitochondrial strength, causing leakage within cells, and activating oxidative stress genes. In addition, this review covers ZnO NPs in food packaging, highlighting their role as antimicrobial barriers against pathogens.</div></div>","PeriodicalId":100942,"journal":{"name":"Nano Trends","volume":"11 ","pages":"Article 100145"},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145026363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

W nanocontacts between nanotip and plate elongated at a tensile speed of 1–9 nm/s under direct-current voltages of 0.9–2.5V. An approximately 10 nm diameter region at a positively biased electrode surface adjacent to the contact became a growth point, and atoms in the region aggregated to form and elongate a nanowire. The maximum width and length of the grown nanowires reached 20 nm and 189 nm, respectively. Saw-edge shape variations were observed in strain-stress relations derived during the growth process, exhibiting that the growth speed of the nanowires depended on stress acting on the nanowires. The present nanowire growth occurred based on the expansion of the wire end due to the atom aggregation promoted by voltage energization with the reduction of growth-suppressing stresses by tensile manipulation. When pulse voltage energization and tensile manipulation were performed alternatively, nanowires growth continued. In this condition, the maximum wire width and length increased to 38 nm and 294 nm, respectively.
