Silver ion antibacterial action mechanism
Silver ions can be regarded as a kind of antibacterial material or substance. The antibacterial effect of materials is generally speaking of the adverse effects and consequences that a certain material has on the vitality of microorganisms. These adverse effects and consequences are concentrated. The manifestation is that it affects the growth, reproduction and death of microorganisms. That is, inhibiting the growth, reproduction or killing of microorganisms. The relationship between antibacterial materials and microorganisms can be regarded as the relationship between microorganisms and the environment, especially environments that are toxic to microorganisms. The antibacterial action mechanism of materials has the following aspects.
(1) Interfering with cell wall synthesis. The important component of the bacterial cell wall is peptidoglycan. The interference effect of antibacterial materials on the cell wall mainly inhibits the cross-linking of polysaccharide chains and tetrapeptides, thereby causing the cell wall to lose its integrity, lose its protective effect on osmotic pressure, and damage the bacteria. And death.
(2) Can damage cell membranes. The cell membrane is an important component of bacterial cell life activities. Therefore, if the cell membrane is damaged or destroyed, bacteria will die.
(3) Inhibit protein synthesis. The protein synthesis process is altered, stopped, and the bacteria die.
(4) Interference with nucleic acid synthesis. Generally speaking, it hinders the replication of genetic information, including the synthesis of DNA and RNA, and the transcription of DNA templates into mRNA.
