Principle of antibacterial

The major antibacterial effect of silver is its partial oxidation and releasing silver ions, which interact with thiol groups of peptidoglicans of bacterial cell wall, and proteins of the cell membrane causing cell lysis. Silver ions can also bind to bacterial DNA preventing its replication and stopping synthesis of bacterial proteins.

When nanosilver close to viruses, fungi, bacteria or bacteriophages, it will attack the cell and damage the Biochemical reaction of bacterial or virus. Slow low dosage free silver ion release continue  Antibacterial property.
