Metal silver ion disinfectant

[Category] Silver metal, silver acetate, silver nitrate, silver protein and silver sulfadiazine

[Structural formula] The molecular structure of silver sulfadiazine is as follows:

[Application] For a long time, silver and its compounds have been used as antibacterial agents

The antibacterial mechanism of silver ions is mainly through the combination of silver ions with bacterial proteins and sulfhydryl groups (-SH) of functional enzymes to form irreversible silver sulfide compounds, which interfere with the normal physiological processes of microorganisms and cause bacterial cell death; silver ions contact the bacterial cell membranes When the cell membrane is negatively charged, relying on Coulomb attraction, the two are firmly adsorbed.

Studies such as Spencer and Mahendra have shown that silver ion disinfectants are effective against Escherichia coli , methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococcus (VRE), viruses and fungi, and the inactivation rate is about 99.

The killing effect of silver ion disinfectant on microorganisms is affected by many factors, such as silver ion valence, pH value of the solution, temperature, organic matter, etc.
