Thin-layer Impedimetric Biosensors for the Free-label Immunoassay
Abstract:
In the present study thin-layer impedimetric biosensors were developed for the free-label immunoassay of Fatty Acid Binding Protein (FABP). This test based on antibody recognition was performed within a thin-layer detection cell between two pieces of conducting glass. Antibodies were immobilized by physical adsorption. The biosensor exhibited obvious change of impedimetric signals due to the adsorbed antibody and subsequently captured antigen. No label of enzyme or aurum nanoparticle is needed. The given equivalent circuit is consonant well with the impedimetric results.
