Heraeus Precious Metals has developed an antimicrobial technology called AGXX, which the company says eliminates bacteria, fungi, viruses, and algae through a catalytic reaction rather than by releasing metal ions or other potentially harmful substances.
Unlike conventional antimicrobial coatings, which often rely on silver or copper ion release and lose effectiveness over time, AGXX operates continuously using humidity and oxygen from the surrounding air.
The process generates reactive oxygen species (ROS) that destroy microorganisms and prevent biofilm formation.
According to Heraeus, this mechanism provides “long-lasting protection against microbial contamination and reduces odor” in textiles and other materials.
The company says AGXX technology can be integrated into textiles either by embedding it into fibers or by applying it through advanced coating and finishing techniques.
Heraeus has formed strategic alliances with textile manufacturers to demonstrate what it describes as “the seamless integration of AGXX into existing production processes”.
These partnerships, the company says, mark an important step in the commercial rollout of AGXX and are helping to accelerate its adoption across healthcare, hospitality, and consumer sectors.
“Appropriately prepared workwear prevents the spread of contagious infections,” the company notes, adding that antimicrobial textiles could help reduce the number of hospital-acquired infections, which cause an estimated 20,000 deaths each year in Germany.
Heraeus also highlights applications in sportswear and air filtration. The company says the technology can neutralize odor-causing bacteria and sweat-derived acids, extending the lifespan and comfort of garments and filters exposed to heavy use.
Martin Danz, head of antimicrobial technologies at Heraeus Precious Metals, says: “With AGXX, the textile industry no longer has to choose between antibacterial, antifungal, or anti-odor functionality as AGXX delivers all three.
“Moreover, it offers a future-proof alternative to metal-free technologies, ensuring long-term regulatory compliance.”
The company says independent tests, including ISO 20743 and AATCC 100 for antimicrobial performance and ISO 17299 for anti-odor capability, confirm that AGXX remains effective after multiple washing cycles.
Heraeus adds that AGXX is compliant with the EU Biocidal Products Regulation (BPR) and holds ECO PASSPORT by OEKO-TEX certification, allowing brands to label finished products accordingly.
“These developments reinforce Heraeus’ commitment to responsible innovation and its leadership in advancing antimicrobial technologies that meet both performance and regulatory standards,” the company says.
