Abstract

A study was conducted to demonstrate surface-imprinted conducting polymers (SIP) microrods for selective protein recognition. Precisely sized cylindrical pores of a track-etch polycarbonate membrane (PCM) filter served as sacrificial microreactor for the synthesis. It was observed that native membranes were hydrophobic in nature and absorbed protein molecules, offering a method for fixing the target protein onto the pore walls by simple physical adsorption. Conducting polymer rods of poly-3,4-ethylenedioxythiophene (PEDOT) doped with polystyrene sulfonate (PSS) were electrochemically grown in the microreactors positioned on the surface of a gold electrode. The PCM was easily removed by dissolution in chloroform after polymerizing the microrods in the pores. The removal of the sacrificial material resulted in the formation of microrods confined to the surface of the gold electrodes ossessing the imprint of the target protein on their surface.
