Maybe we'll see commonly touched surfaces such as door knobs, handles, railings etc. made out of copper.Copper Destroys Viruses and Bacteria. Why Isn’t It Everywhere? - VICE

Weren't silver coins dropped into milk jugs to kill bacteria ?
Tin also.Silver also has some anti-bacterial properties.

I read that the copper bracelets that were advertised to help with arthritis did nothing but the copper gloves were shown to help.I have a pallet of 36 x 120 copper sheets. My fiber laser easily cuts the copper. Time to make some copper gloves.
Jugs themselves were Silver, Persian Empires onward. Milk stayed fresher, longer. No one knew WHY. It just did.
G'mum's dairying goods were mostly "Monel" - a Cupro-Nickel alloy that also has biocidal tendencies far more effective than "indifferent bystander" Stainless steel.
T'other G'mum had an "ice box" lined with Zinc and a countertop to roll-out baked goods also solid Zinc. Decent biocides, both.
NOW we finally know WHY.
Silver's outer-valence shape physically "fits" the weak covalent-bonded O2 molecule so well it snatches it apart, freeing two very much more aggressively-seeking-a-redox-mate "nascent" Oxygen atoms. Bugs get "burned" so to speak.
As to Copper, it's ions are implicated in weakening the formation of the outer membrane a(ny) cell - plant or animal, either one - needs to "stay in its home bag" and function normally.
Copper doorknobs and hand-pulls even more than brass HAD been widely used on schools and other high-traffic public buildings "of quality" for Donkey's Years.
Until bright-plated, looks-brass but may not-be - then Stainless steel got cheaper.
"Cheaper" eh?
You can guess the rest?
Got it in one: "The American disease"
"We are cheaper than..."
