This is a recent interesting paper: https://doi.org/10.1111/php.13767

Showing effectiveness on surfaces, while remaining safe for humans.

I’m following closely the development, it’s still extremely costly to make a product but hopefully will see more adoption in the near future, starting at enterprise level. I have a device in my home, planning to permanently install it in the entrance where we leave shoes & co.

Feel free to dm me if you’re hacking in the space, happy to chat more.
