The development of a biosensor with adequate sensitivity generally requires a biospecific
interaction with high binding affinity. The affinity constants for most antibody-antigen …

Affinity biosensors play a crucial role in clinical diagnosis, pharmaceuticals, immunology,
and other areas of human health. Affinity biosensors rely on the specific binding between …

The label-free amperometric detection of a rabbit IgG antigen by an anti-rabbit IgG antibody
is achieved by observing the electrochemistry at a glassy carbon electrode modified with …

Although most immunosensors which have high affinity antigen–antibody interactions can
perform highly specific and sensitive detection, antibody–antigen bonds are typically too …

We show that the binding of an antibody to its antigen can be controlled electrically in a
reversible manner. The antibody–antigen interaction is monitored by an electrochemical …

An amperometric, enzyme-channeling immunosensor was used to study the qualitative and
quantitative aspects of molecular biorecognition in real time. The immunosensor consisted …

Electrochemical impedance spectroscopy (EIS) combined with a gold electrode array was
developed to detect multiple antibody–antigen interactions. Hepatitis B surface antigen …

Biosensors generally rely on the reaction or attachment of an analyte with a solid support–
usually a bio-functionalized transducer. They can therefore suffer from transport limitations …

Publisher Summary Antibody-based biosensors are based on the principle that antigen–
antibody interactions can be transduced directly into a measurable physical signal. This …

The extension of a generic immobilization technology for the fabrication of antibody-and
receptor-based biosensors is reported. The biosensors utilize polymerized protein films …
