If you create a nm sized pore in a synthetic material like graphene and then put a voltage across it in an electrolyte solution ions will flow unimpeded through the pore to create a current but if at the same time you put through a viral RNA molecule such as Sars-cov-2 then each base interferes with the current in a known manner and you can sequence the bases. This is the technology behind some rapid testing technology.

I had to read this several times just get a basic grasp of its point. There's some incredibly smart people on this planet. It's hard to imagine what the basis would be to even discover this as an option, let alone be able to think far enough ahead to think it's viable too. Amazing.
