DRDO develops Automatic Sanitiser Dispensing Unit and UV Sanitisation Box to fight coronavirus

Defence Research and Development Organisation (DRDO) developed Automatic Mist Based Sanitiser Dispensing Unit and UV Sanitisation Box and Hand-held UV device to fight against COVID-19.

Automatic Mist Based Sanitiser Dispensing Unit:
Centre for Fire Explosive & Environment Safety (CFEES), Delhi has developed an automatic mist based sanitizer dispensing unit. It is a contactless sanitizer dispenser that sprays alcohol-based hand rub sanitizer solution for sanitization of hands while entering the buildings/office complexes, etc. It is based on water mist aerator technology, which was developed for water conservation.
It operates without contact and is activated through an ultrasonic sensor. A single fluid nozzle with a low flow rate is used to generate aerated mist to dispense the hand rub sanitizer. The sanitizer will sanitize the hands with minimum wastage. Using an atomizer, only 5-6 ml sanitizer is released for 12 seconds in one operation.

UV Sanitisation Box & Hand-held UV device:
Defence Institute of Physiology & Allied Sciences (DIPAS) and Institute of Nuclear Medicine & Allied Sciences (INMAS) have designed & developed Ultraviolet C Light-based sanitization box and handheld UV-C (ultraviolet light with wavelength 254 nanometres) device. 
The UV-C will destroy genetic material in COVID-19. The radiation warps the structure RNA which prevents the viral particles from making more copies of themselves. This is environment friendly and is a contact-free effective sanitization method.
