National Institute of Technology Karnataka Surathkal’s professor Arun M Isloor and his research scholar Ibrahim Sayeed developed a disinfectant chamber from an old fridge. They named the disinfected chamber as ‘ZERO-COV.’ Arun said, “The aim is to provide the disinfection technology used in laboratories and hospitals to the doorstep of common man.” He further said that people can make their own disinfection chamber of old boxes or suitcases.
