@slomobile - The idea of using NMR/MMR as a specific SARS-CoV-2 test (wild speculation) would be attractive if this could be engineered into something like a "finger tunnel", where insertion of a digit could produce a result within minutes. The problem would be "how to recognise" the signals in the midst of a lot of other protein/organic noise. Artificial intelligence is a possible method if many COVID-19 patients are identified and samples of blood analysed. The signal levels are going to be ridiculously low, but if fine spectral frequencies are picked out then it might just be feasible. I have floated the diagnostic test idea with an expert in NMR to consider. Resonating these to destruction is even wilder speculation - but not theoretically impossible. I destroyed a 60 KHz crystal that way
(but not discussed with NMR expert!).
I have had a report that the interesting "bio video" I mentioned before sometimes does not open in a browser. I think this is an update (
https://www.youtube.com/watch?v=8uYuNvh_b6c), but you can search YouTube yourselves for "Ninja Nerd Medicine" and "COVID-19" to find it. There are actually two of them. The first is about "pathophysiology" (disease pathway) and the second is "treatment", which includes how to use ventilation to optimise the benefits. They are exceptionally great.
SARS-CoV-2 enters the alveoli "type 2 surfactant" cells (type 1 is the oxygen exchanger) by attaching to the ACE2 receptor in the walls of the type 2 cell. CHLOROQUINE inhibits ACE2 receptors. So you need to take CHLOROQUINE before you are infected. This is like malaria prevention. Another drug REMDESIVIR inhibits "RNA-dependant RNA polymerase" which is how new RNA for the new viral cells is produced by viral action inside the alveoli cell. Both these drugs sound very promising but they have side effects.
The video also has some great Chest X-Ray, CT SCAN, and Ultrasound Scan pictures, showing how the disease shows up diagnostically. And it explains why "Cytokines" (chemical alarm messengers) enter the blood stream and hit the Pituitary in the brain, which in turn raises the set-point for body temperature regulation and causes the fever. That's what Project#1 is looking for.
Lack of surfactant results in collapsing alveoli and creates shortness of breath. A small positive air pressure stops the collapse, especially on end of the exhale. That's where CPAP can help those not yet critical - Project#2. I think the Formula 1 guys might have the technical edge on us!
Edit: The vacuum HEPA filter is an excellent idea.
Edit2: Seems that even NXP have got into the act...
