Yes, I agree. They probably are telling us how much more time they need to do the preliminary lab work before potential commercialization, which as you say, could take much longer (especially if they need regulatory approval from FDA, etc.)
Different antibodies can functionalize the sensor for detecting different things. The inventors only discuss detecting specific maladies, but potentially a whole variety could be screened simultaneously.
2 years till it is available commercially? I admire their optimism but not their hold onto reality. Medical product, new technology, 2 years .... seems very very unlikely.
Microfluidic detectors have been 2 years away from commercialization for at least 6-7 years. I have yet to see one in my doctor's office.
I think they have some great technology and it is certainly worthy of being available. I just highly doubt the final product development and all the necessary testing and approvals will be ready in that period of time.
Excellent two years to market, virus detection as well - does it have to be made special for each type of thing it is to detect or is it simply a receiver and some other device translates ?
Maybe next up - they will be able to do it with out blood - breath, or simply a light wave...
