Questions and answers

Q: Does heating of the solution and instruments take place in the Unit for inactivation of viruses?

A: There is no heating involved during inactivation process. Inactivation occurs at room temperature.


Q: When inactivating viruses in the Unit, does photoactivated methylene blue have a negative effect on medical instruments? Do medical instruments lose their qualities – reflectiveness, hardness, elasticity and others?

A: Photoactivated methylene blue has the property of reacting with organic substances, in particular with RNA or DNA. Inorganic materials – metals, glass, plastic, various alloys, etc. are not affected by methylene blue, even when it is in the activated state, which was proven in our studies.


Q: What is the difference between inactivation of viruses in the Unit and sterilization?

A: Upon inactivation in the Unit, photoactivated methylene blue molecules actively enter into strong bonds with a pair of nucleic acids – guanine and cytosine and block them in the RNA or DNA strands of viruses. Viruses with such inactivated RNA and DNA, even when they enter the human blood, are not able to infect cells and multiply inside cells (replicate). Sterilization means the destruction of all pathogenic agents – microorganisms, viruses, fungi.


Q: Can inactivation in the Unit replace sterilization?

A: Yes, it can. Inactivation of viruses in “the Unit for the inactivation of viruses on medical instruments” has several advantages: reliable neutralization of all types of DNA and RNA viruses; low temperature inactivation mode; can be used to inactivate viruses medical instruments from any material; absolute safety for personnel and the environment; lack of toxicity and allergenicity; medical instruments do not lose their properties (hardness, elasticity, mirroring, etc.). Our studies prove the effectiveness of the Unit, that is, the inactivation of other harmful microorganisms of groups such as fungi, spores, bacteria lose their viability.
