What is it about?

COVID-19 has a global impact and is rapidly spreading. Despite extensive research, there are only few vaccines available and the disease is still spreadable. Around 80 % of patients in India are asymptomatic because of the disease’s lack of symptoms.

Why is it important?

The novel framework is implemented using these methods. The motivation of the proposed work is that bacteria can be killed by TiO2 doped with copper. This sanitizes the atmosphere in hospitals. It can also be used to destroy microorganisms on the roadway. The scope of the proposed work is to cover intravenous masks and catheters to stop COVID-19. Hence, the proposed method of antimicrobial effect uses nano TiO2 for disinfecting COVID affected places.


Thus, a novel methodology is introduced for antimicrobial effect and self-disinfection, which has various praises. Coating the proposed TiO2 filters on toilet seats, floors, and walls is suggested to kill the COVID-19 that comes into contact with hospitals, homes, malls, airports, railways, and road terminals. The airborne filter structures coated with TiO2 or copper doped TiO2 that can be designed to kill the microorganisms. A These can be fitted inside the hospital rooms to filter the air free from microorganisms. They can also be coated on road pavements to kill the microorganisms present there. It can also be coated inside masks and catheters used in intravenous lines to prevent COVID-19 growth.
