polypyrrole (ppy) has been shown to be a superior matrix for fluorescence detection based immunosensors: (i) the fluorescence of polypyrrole and polypyrrole modified by entrapped proteins was almost not detectable when this polymer was excited by near uv 325 nm light; (ii) polypyrrole quenched the fluorescence of such fluorescence agents as fluoresceine 5(6)-isothiocyanate, rhodamine b and enzyme-horseradish peroxidase (hrp) by almost 100% if they were deposited in the solution as a drop at the ppy surface followed by evaporation of the solvent. |
