AGXX - The superior antimicrobial technology against bacteria, viruses and all other microorganisms

Microorganisms can pose a significant health threat as well as harm to the economy. With recent heightened awareness of this serious issue, Heraeus offers AGXX - a superior antimicrobial technology to combat this threat.

The AGXX technology promises an outstanding antimicrobial effect and delivers more benefits in comparison to conventional antimicrobial solutions (e.g. silver-ion- or silver-nano-based products). AGXX provides broadband effect, longer lasting effect and does not release metal ions into the environment.

AGXX is the future in the combat against microorganisms. If you need a solution for a microorganism-caused problem, Heraeus can help you.

What are AGXX-Particles?

AGXX

Heraeus offers AGXX particles as an innovative antimicrobial technology. It kills microorganisms sustainable, is highly efficient and prevents the development of biofilms.

Unlike many other antimicrobial technologies, AGXX works free of pharmaceuticals nor is its effect based on the release of metal ions.

These properties make AGXX ready for use in a wide range of applications, such as face masks, exterior wall paint, air filtration and other needs, enabling you to bring your products to the next level.

Proven advantages of AGXX vs. conventional antimicrobial technologies

How does AGXX work?

AGXX is a highly efficient, catalytically driven antimicrobial technology, based on redox reactions and microelectric field effects. In the presence of air humidity, oxygen is converted into reactive oxygen species (ROS), which react with the microorganisms and kill them. In addition, the existing microelectric field affects important functions of the cell membrane and accelerates the killing of the microorganisms.

Mechanism of action of AGXX

According to the new Biocide Regulation (VO 528/2012), active substances formed in situ are also classified as biocides. Therefore: biocides should be used with care. Always read the label and product information before use.

Successfully tested against more than 130 microorganisms

The antimicrobial effect of AGXX has been successfully tested against more than 130 microorganisms, including the silver- resistant E. coli. The successful testing is only one of many proofs for the superiority of AGXX, made possible by the innovative antimicrobial effect mechanism which is based on strong oxidation. Unlike for example, classical silver systems, AGXX does not allow the formation of any resistance.

In the image, the efficacy of AGXX is visualized by the strong formation of the inhibition zones, also in comparison to pure silver.

Potential Applications for our antimicrobial technology

Antimicrobial technology

What does antimicrobial mean?

Bacteria

Antimicrobial agents kill or inhibit the growth of microorganisms. But what are microorganisms?

Microorganisms are the smallest living beings, that cannot be seen by the naked eye. Most of them exist in unicellular form, but also some exist in multicellular form. They are divided into six different groups:

  • Bacteria
  • Archaea
  • Protozoa
  • Algae
  • Fungi
  • Viruses

Difference between an antibacterial and antimicrobial technology

Often there is no distinction made between the terms antibacterial and antimicrobial, although the difference is quite logical. While an antimicrobial agent works against a wide range of microorganisms, antibacterial agents, as the word suggests, only work against bacteria.

Benefits of an antimicrobial technology

Microorganisms can be harmful to humans and animals: they, for example, cause or spread diseases or infections. Every year, approximately 11 million people die from sepsis, which corresponds to around one in five deaths worldwide. Sepsis can occur as a result of the body´s reaction to an infection.

These risks can be reduced by antimicrobial technology in various areas, such as face masks, medical devices, public transport, air filtration, dental care, and other applications.

Microorganisms not only affect the health of humans and animals, they pose enormous economic consequences every year due to biocorrosion and fouling. Biocorrosion and fouling lead to plant damages, loss of quality and performance as well as increased consumption of raw materials and energy. Every year around 20% of the economic damage caused by corrosion can be traced back to biocorrosion, which corresponds to an annual damage of approximately 307 Billion €. In order to prevent biocorrosion and fouling, antimicrobial technologies are used to ensure the functionality of equipment and enhance the quality of the goods produced.

Comparison of different antimicrobial technologies with AGXX

In addition to their effectiveness, antimicrobial technologies must also meet regulatory requirements in order to achieve long-term and sustainable success in the combat against microorganisms.

Frequently asked questions about our antimicrobial technology

AGXX is a highly efficient, catalytically driven antimicrobial technology, based on redox reactions and microelectric field effects. In the presence of air humidity, oxygen is converted into reactive oxygen species (ROS), which react with the microorganisms and kill them. In addition, the existing microelectric field affects important functions of the cell membrane and accelerates the killing of the microorganisms.

The mechanism of action of classic silver-based technologies is based on the release of silver ions, while the mechanism of action of AGXX is based on a catalytic redox reaction and a micro-electric field and does not form any precious metal residues.

Furthermore, AGXX delivers certain advantages in comparison to silver-based technologies containing

  • No resistance possible
  • Longer lasting effect
  • Effective in sulphurous environments
  • Highly efficient against biofilm formation

Due to the low precious metal content, effectiveness and longevity of AGXX, cost leadership can be achieved in many markets over the lifetime of a product.
