Gold nanoparticles based sandwich electrochemical immunosensor
Biosensors and Bioelectronics, 2010In 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 ...

An electrochemical immunosensor using ferrocenyl-tethered dendrimer
The Analyst, 2006We report here an enzyme-amplified, sandwich-type immunosensor for detecting the biospecific interaction between an antibody and antigen using redox mediation. We employed biotin/anti-biotin IgG as a model immunosensing pair. Partially ferrocenyl-tethered dendrimer (Fc-D), whose ferrocene moiety acts as a redox mediator, was immobilized to the ...

Screen-Printed Electrochemical Immunosensors for PCB Detection
Electroanalysis, 2000An electrochemical enzyme immunoassay for polychlorinated biphenyls (PCB) using carbon-based screen-printed disposable electrodes as the solid-phase for reagent immobilization and also as the signal transducer has been optimized. Horseradish peroxidase (HRP) was conjugated with Ag or Ab and used as the enzyme label.

Disposable electrochemical immunosensor for environmental applications.
Annali di chimica, 2002An Immunosensor for the detection of polychlorinated biphenyls (PCB) has been developed, using carbon-based screen-printed electrodes as solid-phase and signal transducers. The immunosensor realised is based on a direct competitive immunoassay scheme, in which the antibody against PCB was directly immobilised onto the carbon surface of the screen ...

IgY - electrochemical immunosensor based on nanoelectrodes ensembles
2016Abstract It has been recently demonstrated that chicken egg-yolk immunoglobulin Y (IgY) has many immunological properties not only on avian, but also on mammalians, such as human [1]. Since it is easy to insulate (directly from egg yolk – where it is present at a concentration of 10 mg/mL), recently scientists proposed new immunotherapies based on the ...
