Go for it if you like. I think this investor update states that the other projects have progress. And everybody keeps focusing on COVID-19. Which is just ONE of the things the NanoDX sensor can do. Once it is approved it will be handy despite how COVID is going.
If you still have doubts, I'll buy your shares for 6c each and hold them.
