From germicidal boxes to sterilizers, they are developing products to keep the virus at bay Studies have shown that exposure to ultraviolet (UV) light at a wavelength of under 290 nanometres modifies the DNA of microorganisms.
Using this principle, researchers at the Indian Institute of Technology (IIT)-Ropar have developed a germicidal box that can be placed at doorsteps to sanitize every small item brought from the outside, such as groceries and vegetables, and currency notes.
All you have to do is put them in the box for 30 minutes. The spread of covid-19 has made wearing masks, maintaining physical distance and sanitizing every item a necessity.
