    Copper coating turns touchscreens into bacteria killers | In tests, the TANCS was found to kill 99.9% of applied bacteria within two hours. It also remained intact and effective after being subjected to the equivalent of being wiped down with cleansers twice a day for two years.

      Copper is amazing. I was introduced to the copper-up-on-the-ridgeline of a roof many years ago and it is very effective at keeping algae from growing.
      Interesting to read about its effects on bacteria

      Integrating copper as a bacteria killing surface for touchscreens is clever, but is there any research into the evolutionary adaptation likely if this approach is adopted at scale? Or is copper ion cell damage something bacteria cannot evolve around?

      This is why fancy hospitals use copper to coat door handles and railings.

      It’s not new, it’s just expensive.

      Silver works basically the same way, but it’s even more expensive.
