Abstract:
Early POC diagnosis of cancer is demonstrated by using multi-invertase conjugated microsphere labels and a personal glucose sensor (PGS) transducer. The invertase, which catalyzes the hydrolysis of sucrose to glucose, enables the PGS to detect target analytes beyond glucose, and the numerous invertase labels involved in each antibody-antigen binding event lead to significantly amplified PGS readings for sensitive protein detection.
