General method for the entrapment of organic bioactive agents in a metal matrix


Cleantech, Environment, Water Technologies

Development Stage

Prototype completed



  • A new materials technology enables the entrapment of organic biocidal compounds within biocidal silver, resulting in a powerful antibacterial composite: SilverPlus.
  • The new silver composites are more effective than silver alone and their material traits make them particularly suitable for use in the disinfection of closed loop re-circulating water systems and for potable water in emergencies.

Our Innovation

Device for disinfecting re-circulating water system utilizing new biocidal silver composite


Key Features

  • New antibacterial compositions based on common active substances
  • Controlled release of the organic biocidal agents which are entrapped in silver
  • Synergetic microbiocidal activity
  • Reduced environmental fingerprints and burdens
  • Residual disinfection capabilities in the treated water systems

Development Milestones

  • Seeking industry cooperation for commercialization and funding for ongoing research and development

The Opportunity

  • Applications in industrial hot and cold water systems, hot water systems for institutional buildings, swimming pools, aquaculture
