Immunochemical detection using the light-addressable potentiometric sensor

Abstract

Rapid, sensitive and flexible assay systems are needed for immunoassays, receptor-ligand binding studies and DNA probe assays. Filtration capture and sensor detection offer several advantages to these areas. Although dependent on the affinity of the specific binders employed, the sensitivity of these techniques can be in the order of 10(-12) M, and total assay time can be less than 15 minutes.
