Kinda interesting. I wonder if the originator has done more with the idea other than show the technical feasibility of the coating method?
The problem with so much journalism in the health, wellness and nutrition area is that it starts with an idea where somebody has shown there is some effect on some problem. What we (almost) never see is anything to do with how significant the effect may be nor the cost effectiveness of solving the problem that way compared to any other way. In that this article is no different. The article says the solution is quick and cost effective without a bit of supporting evidence. I take their word for it being quick but not about being cost effective.
The wellness industry in particular is given to moving from ‘we can show something happens when you use XYZ’ to ‘everybody must use XYZ for their health’ without any evidence. Nothing could be further from the truth - all this does is start off the next silly fad that has no other purpose than to make money for the providers and boosters.
Copper does have anti-microbial properties -
From Wikipedia “Copper” - Some 355 copper alloys  were proven to kill more than 99.9% of disease-causing bacteria within just two hours when cleaned regularly.
Note my bolding. It still relies on someone diligently cleaning. I guess people will be rushing out to replace all their door handles with copper, but not realising they are probably coated to resist discolouration and fingerprints.
One lot of tap-ware we looked at a few years ago said treated with “electrophoretic lacquer” to retain a consistent, durable, bright metallic finish. In essence you are not touching copper, but the lacquer.
The same applies to modern brass door handles. As we choose not to spend our days polishing metal they are mostly lacquered in the factory.
Hi Guys, you can leave a comment on the website page at the bottom of the article if you wish. You can reach a much larger and diverse audience that way.
From the linked article, bolding added.
A clinical trial by the National Association of Testing Authorities-accredited clinical trial speciality laboratory, 360Biolabs, using the ACTIVAT3D copper on a live sample of SARS-CoV-2 – the virus that causes COVID-19 – found that touch surfaces modified by this process “contact killed” 96 per cent of the virus in just two hours.
The ‘just two hours’ is an interesting period when people come and go frequently in businesses, and when home they would still need to wash or sanitise every time they came in from being out and about, so the benefit seems real but not terribly efficacious in practice. Further, what about the remaining 4% and whether the handle continue to foster contagion.
Good suggestion. Done, awaiting moderation.
Here is an ABC article from 20 March which talks about how long COVID-19 lasts on surfaces
If it was instantaneous, it would make good news…the results aren’t overly inspiring.
