Silver-based antibacterial agents h

Silver-based antibacterial agents have a broad-spectrum and long-lasting antibacterial properties, and do not produce drug resistance, so they are used in various fields. With the advancement of science and technology, the research method of nano silver is constantly updated, and its research craze has been set off. As a new type of antibacterial material, nano silver has not only the advantages of silver antibacterial agents, but also the advantages of nano materials, such as Strong adsorption capacity, surface reaction activity, large specific surface area, etc., so nano silver is easier to adsorb. Compared with elemental silver, nano silver has stronger antibacterial properties. Xu Yingbu et al. Adopted the sol-gel method, using ethyl orthosilicate as the reaction precursor, zinc nitrate and silver nitrate as antibacterial active ingredients, anhydrous ethanol as the solvent as the catalyst, and citric acid as the compounding agent. A silver-zinc composite film was prepared on a common glass substrate by dipping and pulling method, and the film was characterized by ultraviolet-visible spectroscopy and scanning electron microscopy. Finally, it was concluded that the silver-zinc composite transparent film showed excellent performance in antibacterial and bacteriostatic aspects.
