Many metals are contact-antimicrobial
See https://en.wikipedia.org/wiki/Antimicrobial_properties_of_copper https://en.wikipedia.org/wiki/Antimicrobial_properties_of_co... -: Copper and its alloys (brasses, bronzes, cupronickel, copper-nickel-zinc, and others) are natural antimicrobial materials.
And https://en.wikipedia.org/wiki/Oligodynamic_effect https://en.wikipedia.org/wiki/Oligodynamic_effect -: The oligodynamic effect (from Greek oligos "few", and dynamis "force") is a biocidal effect of metals, especially heavy metals, that occurs even in low concentrations.
- fortran77 7y agoYou're welcome to rub your hands with a copper disk after going out in public. I'm going to wash them with soap and water for 20 seconds.
- TheSpiceIsLife 7y agoTotally agree.
- SkyPuncher 7y agoTo be fair, this would be a great fidget toy while out in public.
- DenisM 7y agoHow about Copper-Spinner? Made from organic anti-viral copper. Heals the soul and the hands.
- megablast 7y agoSo, you don’t pass the virus on, but he does? And you think that’s a win?
- laumars 7y agoThe GPs point isn’t meant as a recommendation for the current situation (SARS-CoV-2 isn’t even a microbe), just an explanation of what that disc is.
- heelix 7y agoI believe copper will kill off this one in about 4-5 hours, compared to the 10+ hours of other materials. Not super useful as a hand sanitizer, but nice to know a copper door handle has a nice longer term self cleaning over shorter time frames.
- TheSpiceIsLife 7y agoI’ve pondered lining my entire bathroom with aluminium-bronze sheet. It keep itself fairly clean!
- raxxorrax 7y agoI looked at this and the problem in practice is allegedly that residue from touching creates a film that cancels the effect. So aside from needing to polish it, you still have to clean it after just a few hours for the effect to work. It also doesn't kill germs immediately, it needs a few minutes to work. It still helps though.
