Spread of COVID-19 infection through door handles.


The University of Arizona conducted research in which they concluded that if there is an infected door handle in a mid-size office with 500 employees, it will take 2-4 hours for the infection to spread among 80 percent of employees.

This fact inspired DiscoverSTEM’s young innovators to design a system to disinfect surfaces, including door handles, doorbells, and lift button panels.

DiscoverSTEM Students from Entrepreneurship Program came together to form a team, launch their startup, and commercialize this innovation. These high-school students were able to secure funding from Kubera Capital, a Texas-based Venture Capital firm in February 2022.


To be launched soon.


Patent pending at the United States Patent and Trademark Office (USPTO) and India Patent Office.
