Au nanoparticle-polyaniline nanocomposite layers obtained through layer-by-layer adsorption for the simultaneous determination of dopamine and uric acid. - In: Electrochimica acta, ISSN 1873-3859, Bd. 56 (2011), 10, S. 3693-3699
The layer-by-layer adsorption technique was used to prepare polyaniline (PANI)-gold nanoparticles (AuNP) multilayered structures with different AuNP/PANI ratios. By means of microgravimetric measurements it was found that the amount of the adsorbed species depends on the duration of the AuNP adsorption step. At fixed adsorption step durations the amount of both (PANI and AuNP) materials increases linearly with the number of adsorption steps. Two types of PANI-AuNP multilayered nanocomposites with different AuNP/PANI ratio were studied as electrocatalytic materials for dopamine and uric acid oxidation. The sensitivity of PANI-AuNP for dopamine oxidation was found to depend on type of the nanocomposite whereas for uric acid oxidation the sensitivity remained unaffected by the type of the nanocomposite structure. This result is discussed in terms of the different limitations for both oxidation reactions. By means of differential pulse voltammetry experiments linear concentration dependences of the anodic peak currents were observed for both dopamine and uric acid in the concentration ranges 7-148 mol dm-3 and 29-720 mol dm-3, respectively. In the presence of both analytes no interference effects were detected.

Electrodeposition of pristine and composite poly(3,4-ethylenedioxythiophene) layers studied by electro-acoustic impedance measurements. - In: Electrochimica acta, ISSN 1873-3859, Bd. 56 (2011), 10, S. 3500-3506
Composite layers of poly(3,4-ethylenedioxythiophene) and diamond nanoparticles were prepared by an electrocodeposition procedure from an electrolyte containing the monomer 3,4-ethylenedioxythiophene and a suspension of diamond nanoparticles in acetonitrile/water mixtures. For the in situ monitoring of the deposition process we used piezoelectric quartz crystals with gold electrodes as substrates (electrochemical quartz crystal microbalance, EQCM). The inclusion of the diamond particles increases the stiffness of the layers. This effect can be directly quantified via the electroacoustic impedance of the quartz crystal. We use a mean field model for the interpretation of our EQCM data which yields the complex shear modulus of the composite layers. The volume fraction of diamond (as determined by ex situ XPS) enters as a parameter in the evaluation procedure. Finally, we could estimate the solvent content of the composite layers and the shear moduli of the pure dry PEDOT matrix.
