Could this invention flow from NIH's Brilicidin work?
NIH has an office in Gaithersburg, Maryland and the "swab" inventor, Subhash Dhawan, is also from Gaithersburg. Thus, it seems reasonable to assume she is a government scientist, who has been involved with brilicidin research or, at the very least, she's aware of the brilicidin research.
I also wonder if she came up with this "swab" idea after seeing the high-efficacy of the brilicidin/remdesivir combo?
In terms of a Sars-Cov2 prophylactic, the evidence suggest that her "swab" should have brilicidin on one end and remdesivir on the other.
There is also the possibility of different types of "swabs" for different types of viral afflictions.
This could be a "godsend" for China, Third World and even more advanced countries.
