“…Conventional chemical oxidative polymerization approaches to nanostructured PANI include the use of hard templates such as zeolite channels, 12 track-etched polycarbonate 13 and anodized alumina 14 or soft templates such as surfactants, 15 liquid crystals, 16 thiolated cyclodextrins 17 and polyacids etc. 18 These templates are reported to be capable of directing growth of 1-D PANI nanostructures with diameters smaller than 100 nm.…”

Polyaniline nanospheres (PANI-NS) prepared by morphological transformation of micelle polymerized camphorsulfonic acid (CSA) doped polyaniline nanotubes (PANI-NT) in the presence of ethylene glycol (EG) have been characterized by X-ray diffraction, atomic force microscopy, transmission electron microscopy, scanning electron microscopy, Fourier transform infra-red and UVVisible spectroscopy. A PANI-NS (60-80 nm) film deposited onto an indium-tin-oxide (ITO) coated glass plate by the solution casting method has been utilized for covalent immobilization of biomolecules (cholesterol oxidase (ChOx)) via N-ethyl-N 0 -(3-dimethylaminopropyl) carbodiimide (EDC) and Nhydroxysuccinimide (NHS) chemistry for fabrication of a cholesterol biosensor. The ChOx/PANI-NS/ ITO bioelectrode detects cholesterol in the concentration range of 25 to 500 mg dL À1 with sensitivity of 1.3 Â 10 À3 mA mg À1 dL and regression coefficient of 0.98. Further, this PANI-NS based bioelectrode shows fast response time (10 s), low Michaelis-Menten constant (2.5 mM) and shelf-life of 12 weeks. The spherical nanostructure observed in the final morphology of the PANI-NS film is attributed to hydrogen bonding interactions between PANI-NT and EG.

“…PANI is a polymer obtained from aniline (an oxidant and a strong mineral acid dopant) that has been successfully used in the construction of sensors (Huang et al, 2002;Sazou & Georgolios, 1997;Trashin et al, 2009;Yin et al, 2006); its applications are limited to acidic media (Grennan et al, 2006;Karyakin et al, 1996). According to previous reports, a more efficient way of attaining reproducible film properties is using electrochemical oxidation.…”

“…Polymer films, and particularly those based on substituted aromatic compounds, such as aniline, present interesting characteristics, namely high conductivity, stability, durability, and reproducibility associated with low costs (Bhadra et al, 2009;Casella & Guascito, 1997;Gornall et al, 2009;Grennan et al, 2006;Huang et al, 2002Huang et al, , 2003Šeděnková et al, 2008;Shan et al, 2008;Trashin et al, 2009;Waltman & Bargon, 1986;Yin et al, 2006). Their main drawback is related to their preparation which involves handling of the respective monomers which are potentially hazardous materials.…”

Disposable screen-printed electrodes (SPCE) were modified using a cosmetic product to partially block the electrode surface in order to obtain a microelectrode array. The microarrays formed were electropolymerized with aniline. Scanning electron microscopy was used to evaluate the modified and polymerized electrode surface. Electrochemical characteristics of the constructed sensor for cadmium analysis were evaluated by cyclic and square-wave voltammetry. Optimized stripping procedure in which the preconcentration of cadmium was achieved by depositing at -1.20 V (vs. Ag/AgCl) resulted in a well defined anodic peak at approximately -0.7 V at pH 4.6. The achieved limit of detection was 4 × 10 −9 mol dm −3. Spray modified and polymerized microarray electrodes were successfully applied to quantify cadmium in fish sample digests.

“…Many synthesis methods [8][9][10][11][12][13] have been reported to prepare nanosized polyaniline. The morphology of polyaniline nanofibers can be modified by introducing hard templates [14,15] or structure directing molecules [16,17].…”

Abstract. Nanorods/nanofibers of polyaniline were synthesized via liquid-liquid interfacial polymerization process using ammonium persulphate as an oxidizing agent. Para-toluene sulphonic acid (p-TSA) was used as a dopant during the polymerization process. The spectroscopic characterization (UV-Vis and FT-IR) confirms the presence of conducting emeraldine salt phase of the polymer. The morphological studies were carried out using FE-SEM analysis.
