PSA
I am a PhD, molecular biology, who has worked in this area
for papers like this, esp ones with catchy buzzwords like nanobody, about 1 paper in 100 leads to an actual thing usable in the non academic world
take, say, the journal Analytical Chemistry
there is a paper every few months about immunoassays with sub pg/mL LOD
and none of those papers (Mirkin people ??) lead to anything
my track record: I said Cas9 ultra rapid ultra sensitive Covid tests were bunk and I was right
