He mentioned the use of Cu nano for the masks - over what he felt might be even more effective (Cerium) ?
Why: As Cu was already a proven agent when it comes to filing patents and new TECH with the FDA.
FDA mentioned.
Interesting stuff :)

(Clipped)
Interesting times ahead I reckon.
Cheers and GL genuine holders.
