content: Maybe the next Marvel or DC movie ... but the popular element for electronics seems to be an effective antimicrobial ingredient in medical masks, touch surfaces, etc.Here is DIY application for a commercial-area door handle:Not sure how much effective CU particles are in masks ... but at least one company is making them [Copper Infused Face Mask]:https://www.coppercompression.com/products/copper-infused-face-mask/Also Dave just vlogged on indoor air filters. Maybe some opportunist will add some Cu ... or a Kickstarter scam in the making ... and Dave can de-bunk. Keep the economy going.Refs:https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_touch_surfaceshttps://www.copper.org/education/c-facts/antimicrobial/print-category.htmlhttp://theconversation.com/copper-is-great-at-killing-superbugs-so-why-dont-hospitals-use-it-73103

content: I think this effect is fairly well documented but as far as I know it's not a quick process.

content: 4 hours till they are inactive on a copper surface, so for the last week at work I just sprayed all the door handles before using them with alcohol based sanitiser. Did use a lot in the toilet, spraying the seat, bowl, door handle and the flush button, more because I work with clothed ursines than the virus, as I just used to wipe them down to get rid of the shmoo before.Guys it seems cannot aim, seeing from the liquid on the bowl top, the sides, under the seat, and on the floor. As well unable to change the roll of paper, as evidenced by the brown roll there, with the spare rolls sitting on the tank half used. I walk in now with hand sanitiser, a good handful of paper towel, and spend 3 minutes cleaning before my meditation session, and another 3 minutes afterwards cursing them, and making it look as clean as I want to see it as I leave. Joyce the cleaner sees it the same way, swearing in isiZulu about them being pigs, and worse things impolite to write here. There are only 6 other men using it, seems some of them are really dense, as we have had this discussion many times before.

content: I'm wondering whether there might not be a way to reduce the "kill-time"? Maybe, run some small current thru. Or, when not in use, run more current thru.Supposedly, NY is in a mess because of all the public-transport contact surfaces. Much of that is metal.Another way to sterilize the metal contact surfaces is to put heat traces thru them.

content: Not just Cu, but also Ag, and maybe more so.Nanoparticles of this are considered potentially dangerous however and are banned in the EU.
