Disposable Capillary-fill Device for the Determination of Proteases Incorporating Eliminating Light-shield of Magnetic Beads with Cleavage of the Electrogenerated Chemiluminescence Label-tagged Peptide Probe

This work describes an ECL-biosensing method that incorporates a disposable ECL capillary-fill device with a peptide-cleavage strategy for the determination of the biomarker PSA, which can eliminate the light-shielding of MBs on the ECL biosensor.
