222 nm far UVC has been trending in the US market since the time it has been launched. It is always discerned that anything launched in the market only survives if they are catering to those benefits that the public needs. Any product needs to build trust amongst its customers so that it can thrive in the market. Moreover, at this time of the pandemic, when people are always trying to cushion themselves from any infection, 222 nm safe disinfection technology adds to the beneficiaries of the public.
One of the direct approaches to tackle airborne diseases is to scupper them from the time they are produced. It has come to notice that far UVc lights are efficient in killing pathogens without harming human tissues. Therefore, far-UVC light has a range of biological materials of less than a few micrometers, which is why it can't reach human cells, protects eyes and skin, and is absorbed in the stratum corneum and or ocular tear of the skin. But since viruses are microscopic, far-UVC light can still pierce and kill them. Thus far-UVC light likely has about the same highly effective germicidal properties of UV light but without the association of human health risks.
Point of Discussion
Regarding these features of far-UVC, several groups have proposed that 222 nm far-UVC light, generated with the help of inexpensive excimer lamps, are potentially safe and efficient anti-microbial technology that can be deployed in occupied public places. The biophysically-based mechanistic basis of the far-UVC approach is that light in this wavelength range has a minimal penetration depth. Specifically, far-UVC light is strongly absorbed by proteins with the peptide bond and other biomolecules. Therefore, its penetration ability with biological materials is minimal n comparison.
This limited penetration is still much more prominent than viruses and bacteria, so far-UVC light is as efficient in killing these pathogens as conventional germicidal UV light. However, unlike germicidal UV light, far-UVC light cannot penetrate either the human stratum corneum, the ocular tear layer, or even the cytoplasm of individual human cells. Thus, far-UVC light can't reach or harm living cells in the human skin or eye compared to the conventional germicidal UV light, which can achieve these sensitive cells.
Far-UVC Light in Summary
On the whole far-UVC light is anticipated to have the same anti-microbial properties as conventional germicidal UV light without producing any health effects. Since this is the scenario, far-UVC light can be used in occupied public settings to intercept the airborne transmit from person to person in the form of Covid-19.
When the efficiency of far-UVC was measured, it was observed that it inactivates human coronaviruses if exposed to aerosol droplets of sizes similar to those generated during sneezing and coughing. Moreover, since all coronaviruses have comparable physical and genomic size, a critical determinant of radiation response, it is also hypothesized that both viruses will respond similar to far-UVC light, and indeed that all coronaviruses will respond similarly.
Axenic-UV is one of the leading brands of America, which caters to all the far-UVC products, considering the need of the hour and contribute to fighting against the pandemic through detection and disinfection.
