An affinity biosensor has been prepared from a conjugated copolymer inverse opal consisting of electropolymerized thiophene and 3‐(hydroxymethyl)thiophene monomers, the latter being used to attach biotin to the pore surface (see Figure). Biospecific binding of avidin is demonstrated by monitoring changes in the bandgap spectral peak position caused by Bragg‐diffraction of electromagnetic waves within the structure.
