Contact with contaminated surfaces is one of the most common ways for illness to spread. A person carrying a pathogen touches something, like a doorknob, then another person touches that object and they can be infected by that pathogen. In between these contacts, the pathogen has to survive on the object, and in a large enough quantity to infect another person. Dustin Gilbert, assistant professor of materials science and engineering, wants to make it impossible, or at least unlikely, for pathogens to survive on a surface.
“If you come into contact with a surface containing pathogens, you could get sick from it, so it’s important to have surfaces that are inhospitable environments for pathogens so they just die quickly rather than being picked up and infecting another person,” said Gilbert. Continue reading
