Customised antimicrobial solutions to keep surfaces clean

Sciessent's customised Agion antimicrobial solutions incorporate silver, copper and other elemental ions into a zeolite carrier.

The ions exchange with other positive ions (often sodium) from the moisture in the environment, effecting a release of the antimicrobial elements "on demand".

The patented multi-faceted zeolite crystal carrier provides a three dimensional release mechanism (Figure 1) that provides efficient release of ions independent of particle orientation in the substrate.

Figure 2 shows the ion exchange process. Zeolite crystals containing elemental ions are randomly oriented and distributed through the surface of a fiber, polymer or coating. In conditions that support bacterial growth, positive ions, in ambient moisture, exchange with elemental ions at reversible bonding sites on the zeolite. The exchanged ions are now available to control microbial growth.

Fighting microbes in three ways

Elemental ions attack multiple targets in the microbe to prevent it from growing to a destructive population.

This tri-modal action fights cell growth in three ways:

  1. Prevents respiration by inhibiting transport functions in the cell wall
  2. Inhibits cell division (reproduction)
  3. Disrupts cell metabolism

Depending on the microorganism, Agion antimicrobial technology has been shown to initially reduce microbial populate ions within minutes to hours while maintaining optimal performance for years.
