Strong antibacterial activity with Ag+ ions

Decopan Antibacterial laminates kill bacteria with Silver ions.

Bacteria-destroying effect of silver ions is connected with three mechanisms:

  1. Interaction with the bacterial cell envelope, destabilization of the membrane, loss of K+ and decrease of ATP level, bonded with phospholipids
  2. Interaction with nucleic acids and enzymes in the bacteria cell
  3. The production of reactive oxygen species (ROS)

Silver ions interact with bacterial inner membrane, where the cytoplasmic membrane is seperated from the cell wall after the interaction.

Silver ions support antibacterial activity strongly (e.g. approved activity in staphylococci within 30 minutes (Randall CP)) by the above mentioned mechanism trio.

Performance testing conducted in accordance with JIS Z 2801:2012

The JIS Z 2801 (ISO 22196), is the most commonly chosen method to test the antimicrobial hard surface performance with a very sensitive procedure.

The procedure starts with inoculation of control and test surfaces with Gram-positive and Gram-negative bacteria in a suspension of standardized dilution, cultured in liquid medium.

Antimicrobial characteristics of the test surface is quantized by calculated levels of antimicrobial activity after 24 hours; during which, inoculated test and control surfaces are alowed to incubate undisturbed in a humid environment.
