AGXX, the antimicrobial technology from Heraeus Precious Metals, protects surfaces and textiles against germs and shows a long-lasting effect against bacteria, viruses, biofilm formation as well as resistant germs. The technology is based on redox reactions and microelectric field effects caused by the electrochemical interaction between two precious metals. In the presence of atmospheric humidity, oxygen is converted into reactive oxygen species that react with and kill microorganisms. In addition, the microelectric field present interferes with important cell membrane functions and accelerates the killing of microorganisms. Unlike conventional technologies, AGXX's mechanism of action is based on a catalytic reaction rather than the release of substances such as metal ions.
To date, antimicrobial activity has been demonstrated against more than 130 microorganisms, including bacteria, viruses, algae, and fungi. AGXX has also been successfully used against silver-resistant E. coli strains, the multi-resistant germ methicillin-resistant S. aureus (MRSA) or CoV2 viruses, which can be attributed to its catalytic mechanism of action and the generation of oxygen free radicals. The application of AGXX also prevents biofilm formation, which has already been successfully demonstrated in use against Legionella.
AGXX is applicable on a particle basis in various materials. As a particle in powder form, it is particularly well suited for use in textile or polymer filters. In addition, AGXX can also be successfully impregnated onto various types of activated carbon granules and pellets, which can be easily used in activated carbon-based water filters. In this way, AGXX effectively helps to prevent the spread of pathogens in an effective and long-lasting manner, as well as to significantly extend product lifetimes. AGXX can also be used effectively in other applications: in addition to filters, the wide range of applications for AGXX also includes textiles, plastics, facade and antifouling paints, air-conditioning technology, protective masks, medical products or sanitary equipment.
