“…Some conducting polymers are doped and/or covalently or physically modified by bionanomaterials, especially proteins and nucleic acids, which exhibit unique catalytic (Malinauskas, 1999) or affinity (Ramanavičienė and Ramanavičius, 2004) properties that can be easily employed in the design of biosensors. Among other conducting polymers, polyaniline is often used as an immobilizing substrate for biomolecules (Geise et al, 1991) and as an efficient electrocatalyst (Yuan et al, 2007). However, to detect bio-analytes at a physiological pH, biosensing materials must be electroactive in neutral environments, unlike polyaniline and polythiophene.…”

“…Later, the same approach was used to combine PANI and mercaptoethane-sulfonate-stabilized Au-and Ag NPs [18], citrate-stabilized Au NPs [20,22], polyamidoamine-encapsulated Pt NPs [19], and ascorbate-stabilized Pd NPs [21]. Most of the studies have so far focused on PANI because of its solubility in aqueous solutions and simple processing.…”

“…Since the works of Rubner et al [4][5][6][7], conducting polymers (CPs) were also intensively involved in similar studies by taking advantage of the CPs charged state (usually positively charged chains for oxidized CPs) and their high electric conductivity. CPs in combination with anionic polyelectrolytes [8][9][10][11][12][13][14][15] or other negatively charged species, i.e., anion-stabilized metallic NPs [16][17][18][19][20][21][22][23][24], metal oxide NPs (e.g., V 2 O 5 [25,26], TiO 2 [27,28], and ZnO [29,30]), magnetic NPs [31,32], CdS [33], polyoxometallates [34,35], and polyoxometallate-stabilized metallic NPs [36][37][38][39] were studied in view of different applications.…”

Layer-by-layer (LbL) deposition is a convenient technique for the formation of ultra thin nanocomposite layers containing metallic nanoparticles (NPs) and conducting polymers (CPs). The advantages of this approach for producing composite layers suitable for electroanalytical applications are discussed. Examples of electroanalytical applications of LbL-deposited composites are presented. Composite layers consisting of polyaniline (PANI) and Pd NPs are used for hydrazine oxidation. The PANI-Au NPs system is applied for dopamine (DA) and uric acid (UA) oxidation. Electroanalytical applications of nanocomposites 349Fig. 3 (a) Cyclic voltammograms measured in 0.5 M H 2 SO 4 after the deposition of each PANI layer in the course of the formation of 6-bilayer Au NP-PANI nanocomposite structure on glassy carbon electrode.

Electrosynthesis and characterization of polymer films on silicon substrates for applications in micromanipulation

Aniline and p-phenylenediamine were electrochemically oxidized in aqueous solutions by potentiodynamic deposition using Cyclic Voltammetry (CV) technique Resulting polymer films electrodeposited on Si substrates were identified by infrared spectroscopy as polyaniline and poly(p-phenylenediamine) films. Cyclic voltammograms demonstrated that poly(p-phenylenediamine) films are non conductive contrary to polyaniline films which are conductive and electropolymerized through an autocatalytic mechanism. The morphological features (thickness, roughness, morphology) of the electrodeposited polymer films were determined using Profilometry, Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). Adhesion force properties of polymer films were also studied by means of force-distance curves obtained by Atomic Force Microscopy. The influence of some experimental parameters (potential scan speed, number of potential scans) was also studied. Thus, it was shown that the potential scan speed strongly influence both morphological features and force adhesion, when the influence of the number of potential scans was less important. Under optimal conditions, it was possible to obtain very adhesive polymer films that could be useful for the micromanipulation of Si objects.2
