DHRUVs: UV based Sanitizer by DRDO to sanitize phones

The Research Centre Imarat (RCI) of Defence Research Development Organization (DRDO) has developed Defence Research Ultraviolet Sanitizer (DHRUVS).

Highlights

• The RCI of DRDO based in Hyderabad has developed a Ultra Violet Cabinet to sanitize mobile phones, laptops, iPads, passbooks, challans and paper. 
• It can also be used to sanitize currency notes and papers. 
• It provides 360-degree exposure to UV rays to the objects placed inside the cabinet.
• DHRUV is a contactless ultraviolet sanitization cabinet that is highly useful to sanitize electronic gadgets.

How does UV kill virus?

• After the spread of COVID-19, several UV technologies have emerged to disinfect the daily use objects. 
• In China, buses are being disinfected with UV light technology every night after their use.
• The technology where Ultra Violet is used as disinfector is called Ultra Violet Germicidal Irradiation (UVGI). 
• The UV light is weak on the earth’s surface as it is blocked by sunlight. Also, UV light is harmful to humans.
• The short wavelength UV are generally the germicidal UV. 
• They are between the wavelength 200 nm and 300 nm. 
• They are highly absorbed by nucleic acids. 
• When absorbed, the nucleic acids lose their capability of replication. 
• Also, the nucleic acid disintegrates shortly leading to death of the organism.
