Nano-silver antibacterial agent is to achieve nanoscale metal particle elemental silver, about 25 nanometers in diameter mostly. Then the use of special technology, nano-silver into a carrier to form a solution.
Origin
Silver Nanoparticles Antimicrobial originated from the ancient times people began to use, it was found that silver and copper vessels retained water should not deteriorate, and later the palace of your time and get used to eat the rich silver chopsticks, folk and wear jewelry made of silver, Chinese folk very early recognized the silver has antibacterial effect.
Definitions
Refers to the ability of nano-silver antibacterial agent within a certain time, so that certain microorganisms (bacteria, fungi, yeasts, algae and viruses, etc.) necessary to maintain growth or reproduction below the level of chemicals. Nano-silver antibacterial agent is a substance or product has bacteriostatic and bactericidal properties.
Antibacterial principle
Contact reaction antibacterial mechanism: silver ions contact reaction, resulting in the destruction of microorganisms common components or produce dysfunction. When a small amount of silver ions to reach the microbial cell membranes, because the latter with a negative charge, relying on Coulomb attraction, so that the two strongly adsorbed silver ions penetrate the cell wall into the cell, and react with SH groups, so that protein coagulation, damage cells synthase activity, cell death and loss of the ability to proliferate. Silver ions can damage microbial electron transport system, respiratory system and mass transport systems.
Feature
Potent bactericidal, repair and regeneration, broad-spectrum bactericidal, permeability, durability, no drug resistance.
