Electrochemical synthesis of polyaniline nano-network on α-alanine functionalized glassy carbon electrode and its application for the direct electrochemistry of horse heart cytochrome c

Endurance training blocks uncoupling protein 1 up-regulation in brown adipose tissue while increasing uncoupling protein 3 in the muscle tissue of rats fed with a high-sugar diet

“…To obtain further information and control regarding the SAM characteristics, the dielectric constant (e) and thickness (d) of the thiol film adsorbed on the gold substrate were investigated through SPR (Bruijn et al, 1991). The values found for e and d were 2.17 and 13.3Å, respectively, for surface coverage G of 26.6 10 À 12 mol cm À 2 , which are in agreement to the literature (Bruijn et al, 1991;Zhang et al, 2009) indicating a good quality in 11-MUA SAM formation.…”

Synthesis of a novel electrode material containing phytic acid-polyaniline nanofibers for simultaneous determination of cadmium and lead ions

“…V is associated with the conversion between the emeraldine and pernigraniline forms of PANI; and peak B1/B2 at around 0.5 V results from the oxidation/reduction of the unstable structure of PANI. These typical peaks are consistent with the previous results for PANI [27,42]. To further confirm the surface modification of the electrodes and the charge transfer rate at the electrode/electrolyte interface, EIS experiments were performed using the [Fe(CN) 6 ] 3-/4couple as the redox probe [43].…”

β-Cyclodextrin inclusion complex as the immobilization matrix for laccase in the fabrication of a biosensor for dopamine determination

“…To understand clearly the electrical properties of the electrodes/solution interfaces, the Randle's equivalent circuit (inset of Fig. 4) was chosen to fit the obtained impedance data [51,52]. In the Randle's circuit, R ct , W, C dl and R sol represent the charge transfer resistance, the diffusion impedance, the interfacial capacity and the electrolyte resistance, respectively.…”
