Abstract:
This work describes a general methodology for enhanced enzyme-linked immunosorbent assay (ELISA) that integrates enzyme-coated microparticle probes for robust yet highly efficient signal amplification and a handheld pH meter for a simple, portable, quantitative readout. Its utility is well demonstrated with the detection of the target protein with a 14-fold enhancement of sensitivity in comparison with the conventional optical ELISA.
