摘要：

The present concept of chemical sensor technology is broadened, which makes it compatible with a wide variety of reagent-based assays, including those with irreversible molecular recognition mechanisms. The renewable chemical sensor system uses minute amounts of beads, on which the reagent is adsorbed and the analyte becomes preconcentrated and monitored. Spent beads are discharged after each use and the sensor surface is renewed by injecting a new portion of fresh bead suspension.
