What about bathroom doors that are touched constantly?

Use your foot. https://old.reddit.com/r/mildlyinteresting/comments/1kb994/t...

I use my elbow. It is the same recommendation as to cough to your elbow. You do not touch with your elbow on yourself or others so it is generally safe.

Unfortunately not always practical due to poorly designed handles and lock mechanisms. I usually "sacrifice" my little finger for this when I have to use my hands, with the theory that I'm much less likely to put that finger in my mouth or eye etc.

Sounds like a problem not worth solving? In my wework the handles get wiped down as per the cleanign protocol. Takes what, a second? The costs are marginal.

Where I think this kind of idea tries to make its case is in places where cleaning is infrequent, inconsistent, or happens long after peak use

The TiO2 will likely rub off and need regular replenishment. Also, the alternative here, sensor-operated or button-operated automatic doors are already widely used. I wonder who this is meant for?

Motion sensors and push plates aren't perfect, but they remove the contact vector entirely instead of trying to mitigate it after the fact

My "Plan B" is the paper towel I dried my hands with. Though bathroom layout, missing trash cans, and lack of paper towels occasionally foil that.

An interesting take. There is also brass and coppers that self-sanitize, albeit more slowly: https://pmc.ncbi.nlm.nih.gov/articles/PMC11279221/

And for metal surfaces which are not self-sanitizing by nature, like steel, there are coatings which can be applied to achieve the same effect. This is often used in public transport.

Or, you know, just use brass: https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_tou...

Not sure how quickly the one from the post takes, but according to the Wikipedia article, brass disinfects "within two hours or less". I could see plenty of transmission within one to two hours. Perhaps it is a difference of speed?
