The Germicidal Power of UVC
That UVCs can be used for air and water sanitization has been known for a long time; the first uses for water sanitization, for example, date back to the early 1900s.
With the spread of the COVID-19 SARS virus pandemic, interest in the sanitizing efficacy of UVC beams has increased exponentially as have related efficacy studies.
In this article from the Don Gnocchi Foundation, "Coronavirus, demonstrated high germicidal power of ultraviolet rays"takes stock of the research on the subject.
You can also find an interesting study from Columbia University about the role of UVC in preventing the spread of Coronavirus.
It must be said, however, that UVC must be handled with great care; the difference between a beneficial effect and one that is harmful to humans is a matter of just a few nanometers. Therefore, we recommend exploring the topic carefully, for example by reading this article by several eminent experts.
UVC e Fotocatalisi:
L’Evoluzione Finale della Sanificazione Ambientale
Extensive research proves that photocatalysis is effective against a broad spectrum of organisms, such as Gram-negative and Gram-positive bacteria (including endospores), fungi, algae, protozoa, and viruses. It is also capable of inactivating prions and neutralizing microbial toxins.
More specifically, photocatalysis does not simply kill bacterial cells; it decomposes them. The killing mechanism works by degrading both the cell wall and the cytoplasmic membrane.
Photocatalytic filtration, with its integration of UVC and photocatalysis, stands as the state-of-the-art for air purification. It moves past basic mechanical filtration toward the actual destruction of airborne pollutants.
