Abstract

The present work demonstrates the possibility of employing a tyrosinase biosensor as a label detector for a continuous heterogeneous flow immunoassay. The tyrosinase biosensor monitors the phenolic product liberated by an alkaline phosphatase label in a non-competitive flow immunoassay for digoxin.
