Inorganic antibacterial agent

Sterile antibacterial agents can be divided into 3 categories: metal ion antibacterial Antibacterial agent hongda wipes ore in egypt, metal oxide antibacterial agent and photocatalytic antibacterial agent. Containing metal Ionic antibacterial agents mainly use metal ions such as silver, copper and zinc. The antibacterial ability of the body, the antibacterial ability of metal oxide The research started late describes it, and it has been determined that the metal oxide possesses antibacterial properties all clean china wet wipes blue color. Compounds include MgO, CaO, ZnO [14, 15], CuO, NiO, and so on. Photocatalytic antibacterial agents are mostly N-type semiconductors, such as: TiO2, CdS, SnO2 etc. Most of the inorganic antibacterial agents need to be used Nano treatment. At present, the nano treatment process of inorganic antibacterial agents Mainly include two kinds of biological method and physical chemical method. As shown in Figure 1, the biological method to prepare nano-inorganic antibacterial agent particles Granules are mainly processed by grinding, boiling, and filtering the plant body Then, add the precursor material of the nanoparticle to make it in the plant extract Inorganic nanoparticles with antibacterial properties are formed. Specific methods for preparing nano-inorganic antibacterial particles by physical and chemical methods The methods are more diverse, mainly using the oxidizing and reducing Physical and chemical properties such as sex and solubility, generating stable nano-inorganic antibacterial Particles. Table 1 shows that the preparation of inorganic antibacterial nanoparticles is more common at present The physical and chemical methods used. Generally speaking, the reason for the good antibacterial performance of nano antibacterial materials It has a large specific surface area and can fully contact with bacteria [16]. There are many opinions on the antibacterial mechanism of antibacterial nanomaterials: such as antibacterial agents Destruction of bacterial cell wall and cell membrane; for bacterial organelle function Changes and so on. However, these mechanisms are only speculations, and further research is needed to determine them. Figure 2 is an example of the antibacterial mechanism of NPs Some speculations.
