The nonphotodriven electrochemiluminescence (ECL) imageology
necessitates
concentrated coreacting additives plus longtime exposures. Seeking
biosafe and streamlined ensembles can help lower the bar for quality
ECL bioimaging to which call the crystallized endo-coreaction in nanoreticula
might provide a potent solution. Herein, an exo-coreactant-free ECL
visualizer was fabricated out in one-pot, which densified the dyad
triethylamine analogue: 1,4-diazabicyclo-[2.2.2]octane (DABCO) in
the lamellar hive of 9,10-di(p-carboxyphenyl)anthracene
(DPA)-Zn2+. This biligated non-noble metal–organic
framework (m-MOF) facilitated a self-contained anodic
ECL with a yield as much as 70% of Ru(bPy)3
2+ in blank phosphate buffered saline. Its featured two-stage emissions
rendered an efficient and endurant CCD imaging at 1.0 V under mere
0.5 s swift snapshots and 0.1 s step-pulsed stimulation. Upon structural
and spectral cause analyses as well as parametric set optimization,
simplistic ECL-graphic immunoassay was mounted in the in situ imager
to enact an ultrasensitive measurement of coronaviral N-protein in both signal-on and off modes by the privilege of straight
surface amidation on m-MOFs, resulting in a wide
dynamic range (10–4–10 ng/mL), a competent
detection limit down to 56 fg/mL, along with nice precision and parallelism
in human saliva tests. The overall work manifests a rudimentary endeavor
in self-sufficient ECL visuality for brisk, biocompatible, and brilliant
production of point-of-care diagnostic “Big Data”.
