Good on these guys for bringing attention to this, but overall this is a strange article that half reads like a promotional piece.
The anti-bacterial nature of many metals is fairly well known going back decades, especially for Group 11 elements[Copper, Silver, Gold] or their alloys.
From what I see they are taking existing doorhandles and 3D printing a 5mm layer of copper over the top for $50-$100 a piece? That's more than the cost of a full copper doorhandle bought down the road.
If replacing handles was of most utmost importance rather than buying new, it would be far less to get copper, silver or gold electroplating done and likely to last a lot longer, metal 3d printing is tough to do and in its infancy.
On the whole this feels like an attempt to capitalise on a situation and get some free publicity rather than offering anything substantially new. The huge "activated copper" promotional sign next to the door in the article probably gives it all away. Can anyone comment on what "activated copper" actually is compared to straight up old copper?
