For #1, I totally agree, used B cells as an example, and also implantable devices/sensors could bring more challenges (foreign body response, encapsulation, a big issue for implantable sensors). I am thinking more of a new virus detector that can be used in vitro or outside that can automatically adapt to viral changes (mutations). Let's call it "molecular morphing" virus detector, if you will (https://www.researchgate.net/figure/Principles-of-the-molecu...).
For #2, sweet! Thanks for sharing! The new virus detection platform could be used to create personalized vaccines, yes.
For #2.1, oh. Software can definitively do things faster like try million iterations until they find the "perfect match" or strong bond (from my previous comments) for viral spike proteins.
For #2.2, also agree, I am more interested in the detection/screening side of things for diseases in general.
