Advances in electrochemical immunosensors

2019
Immunosensors are compact tools on which antibody and antigen interactions are formed. The specific interaction between antibody and antigen is detected by using a transducer and an electrical signal is measured. This specific interaction between these molecules makes immunosensor very attractive for several applications in different fields ...

Electrochemical impedance spectroscopy of polypyrrole based electrochemical immunosensor

Bioelectrochemistry, 2010
Polypyrrole (Ppy) has been shown as a matrix for label-free electrochemical immunosensor based on electrochemical impedance spectroscopy (EIS) measurements. The immunosensing system model presented here was based on bovine leukemia virus (BLV) protein (gp51) entrapped within electrochemically-synthesized polypyrrole (Ppy/gp51).

Gold nanoparticles based sandwich electrochemical immunosensor

Biosensors and Bioelectronics, 2010
In this report we have used gold nanoparticles (AuNPs) to covalently attach an antibody (Ab(1)) using a spacer arm. The AuNPs/Ab(1) modified gold electrode was used for a sandwich electrochemical immunoassay. The detection was done using cyclic voltammetry and impedance measurements using Horse Radish Peroxidase (HRP) as enzyme label on secondary ...

Separation-Free Electrochemical Immunosensor Strategies

Analytical Letters, 2000
ABSTRACT The simplification of the assay strategy is an essential development for the commercial success of immunosensors. The problems associated with assay simplification stem from the fact that immune recognition is not accompanied by an easily detectable event. Direct methods such as those based on optical systems have circumvented such problems by

Advances in electrochemical immunosensors

Electroanalysis, 1997
AbstractThe developments in the field of electrochemical immunosensors and immunoassays are reviewed. The enzyme labels suitable for amperometric, potentiometric and conductimetric detection are mentioned. Indirect immunosensors (i.e., that involving enzymatic or electroactive labels) use either heterogeneous or homogeneous formats.
