Metal‐ and metal‐oxide‐based nanoparticles, surface‐to‐volume is able to distinguish bacterial cells from mammalian cells and can provide long‐term antibacterial and biofilm prevention. These nanoparticles elicit bactericidal properties through the generation of reactive oxygen species (ROS) that are able to target physical structures, metabolic pathways, and DNA synthesis of prokaryotic cells leading to cell death. In this progress report, a critical analysis of current literature on antimicrobial effect of metal and metal‐oxide nanoparticles are examined. Specifically, the antimicrobial mechanisms of metal ions and metal nanomaterials are discussed. Antimicrobial efficiency of nanomaterials is correlated with the structural and physical properties, such as size, shape, and/or zeta potential. A critical analysis of the current state of metal and metal‐oxide nanomaterial research advances our understanding to overcome antibiotic resistance and provide alternatives to combat bacterial infections. Finally, emerging approaches to identify and minimize metallic poisoning, specifically for biomedical applications, are examined.1e:T53f,Developing in situ disinfection methods in vivo to avoid drug-resistant bacteria and tissue toxicity is an urgent need. Here, the photodynamic and photothermal properties of the chitosan-assisted MoS₂ (CS@MoS₂ ) hybrid coating are simultaneously inspired to endow metallic Ti implants with excellent surface self-antibacterial capabilities. This coating, irradiated by only 660 nm visible light (VL) for 10 min, exhibits an antibacterial efficacy of 91.58% and 92.52% against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), respectively. The corresponding value is 64.67% and 57.44%, respectively, after irradiation by a single 808 nm near infrared light for the same amount of time. However, the combined irradiation using both lights can significantly enhance the efficiency up to 99.84% and 99.65% against E. coli and S. aureus, respectively, which can be ascribed to the synergistic effects of photodynamic and photothermal actions. The former produces single oxygen species under 660 nm VL while the latter induces a rise in temperature of implants, which can inhibit the growth of both E. coli and S. aureus. The introduction of CS can also promote the biocompatibility of implants, which provides a facile, rapid, and safe in situ bacteria-killing method in vivo without needing a second surgery.1f:T42f,The aim of this study was to investigate the antibacterial activity of black pepper essential oil (BPEO) on Escherichia coli, further evaluate the potential mechanism of action. Results showed that the minimum inhibition concentration (MIC) of BPEO was 1.0 μL/mL. The diameter of inhibition zone values were with range from 17.12 to 26.13 mm. 2 × MIC treatments had lower membrane potential and shorter kill-time than 1 × MIC, while control had the highest values. E. coli treated with BPEO became deformed, pitted, shriveled, adhesive, and broken. 2 × MIC exhibited the greatest electric conductivity at 1, 3, 5, 7, 9, 11, and 13 h, leaked DNA materials at 4, 8, 12, 16, 20, 24, and 28 h, proteins at 4, 6, 8, 10, 12, 14, and 16 h, potassium ion at 0, 0.5, 1, 1.5, and 2 h, phosphate ion at 0.5, 1, 1.5, and 2 h and ATP (P < 0.05)
