MAIN FEATURE

Disinfecting activity based onphotocatalysts

The antimicrobial function based on the principle of photodynamics has been known since the 19th century. Its basics have been used in various fields of medicine, including dentistry, ophthalmology and cancer treatment.

The phenomenon of photodynamics uses special photocatalysts that have the ability to absorb light in the visible range of 400-700nm and effectively convert oxygen present in the air into oxygen radicals or singlet oxygen. The oxidative effect of these reactive oxygen forms is used to kill microorganisms.

The photocatalysts implemented in the production of AS-100 and AS-100 Clear tapes can produce singlet oxygen with an efficiency of up to 99%. The range of gaseous singlet oxygen is approximately 1 mm, so it is large enough to destroy all microorganisms on the surface, but also small enough not to be released uncontrolled into the surrounding space.

Singlet oxygen causesno microbial resistance

The undoubted advantage of singlet oxygen is the fact that it is a mild oxidant. It can effectively destroy germs without aging the material prematurely. It does not require moisture for its functionality, therefore AS-100 tapes can be used on many surfaces that are generally dry. The key fact is that by now there is no microbial resistance to singlet oxygen and it is not expected to be any – all thanks to a non-specific working principle. This is especially important due to the increase in the number of multi-resistant strains of bacteria these days.

Ag/Zn/Cu

Silver, zinc and copper ions are often used for antimicrobial purposes – mainly in medicine. In many cases, however, they cannot be used because only liquid enables the efficient transport of ions to germs, so they can only be used in humid conditions. Their molecules are also constantly released into the environment, which has led to appearance of reports about the development of the resistance of microorganisms.

TiO2

The antimicrobial effectiveness of titanium dioxide is based on the photocatalytic effect of this compound. As a result of the activation of titanium dioxide, oxygen radicals are formed that can effectively deactivate germs. However, higher reactivity of radical oxygen species causes them to attack also plastic surfaces. UV-A radiation, through which titanium dioxide is activated, also penetrates the tissue layers of skin and eye – damaging them. When using this technology, it is necessary to maintain special safety conditions.

UV-C

The antimicrobial activity of UV-C radiation is based on the induction of strand breaks in the nucleic acid chains and thus causes a bacteriostatic or virucidal effect. However, as with the use of titanium dioxide, they can only be used under specific safety conditions.

Biocides

The effectiveness of biocides like benzalkonium chloride, triclosan, isothiazolinones and chlorhexidine is based on germs “poisoning”. It is necessary to avoid any concentration of these toxic substances both in the ecosystem and in the human body.
