Farmroid’s (222-230nm)-Band Far-UVC LED that can inactivate viruses and germs, without causing damage to other living bodies.
- To manufacture reliable semiconductor UV light sources for special wavelength emission which is ineffective to living body (humans and animals) but can inactivate viruses and germs.
- AlGaN-based Far-UVC LED neither emits any hazardous gas nor CO2 which is unsafe to the environment.
- Smart and clean UVC LEDs are easy to install and can be used as a safe product for sterilization compared to other sterilization methods, i.e., Hg-UV lamps and Excimer UV Lamps.
- Involves agricultural application, controlling the plant diseases by triggering the plants to produce phytochemicals.
Impact of Far-UVC on Germs and Viruses (Sterilization and disinfection)
When the UV Light falls on the germs/ viruses, it is absorbed by its DNA/RNA, forming a dimer by covalent bonding of adjacent thymine bases. Thus, disrupting the sequence of bases in its RNA/DNA interfers with the virus/germ’s replication. An increase in the number of these dimers on the germ/ virus’s DNA/RNA, suppresses the growth of the germs/ viruses, making it harmless, or in other terms, called inactivation of viruses and germs inclduing SARS-CoV-2.
Impact of Far-UVC on Humans
The outermost layer of human skin is the Stratum corneum consisting of hard protein keratin of minimum thickness of 10 to 20µm. Since the virus is less than 0.1 µm in diameter and human skin cells are 10-30 µm in diameter, UV light of 220-230 nm penetrates the viruses and inactivates it. However, UV rays of 220 to 230nm cannot penetrate and damage human skin cells, as it is absorbed by the outermost hard protein layer(keratin) before it could reach the underlying living cells.
The irradiation test of Far-UVC LED will be carried out to find out its practical use or its effect on the living bodies including human body. Details of such testing will be released soon.
