| Abstract |
Based on the strong interaction of noble metal particles with the sulphur atoms of thiophene derivatives, platinum nanoparticles (Pt-NPs)-dispersed poly(3-methylthiophene) (P\3-MeTh\) thin films have been successfully prepared. Evidence of the Pt-NPs confinement in the polymer was provided by the electrocatalytic activity of the modified electrodes towards the dissolved oxygen reduction reaction. The efficient immobilization by self-assembly of thiolated oligonucleotides on the embedded Pt-NPs could be monitored by electrochemical quartz crystal microbalance (EQCM) as well as the subsequent hybridization with the complementary sequence. The good conducting properties and high surface area of P(3-MeTh)/Pt-NPs modified electrodes also allowed the detection of both processes by cyclic voltammetry. (C) 2011 Elsevier B.V.
