Abstract
A renewable immunosensor consisting of an 'epoxygraphite' biocomposite cont
aining silver and tetracyanoquinodimethane (TCNQ) is described. These compo
unds enhance conductivity allowing the use of a smaller potential (0.28 v)
which, in turn, enhances selectivity. This sensor, which may be renewed by
simple polishing of its surface, was employed to detect human IgG using per
oxidase-coupled anti-human IgG.
