“…Such a 20-30 mV shift has been assigned to a strong interaction of glucose with Ni II (OH) 2 [26,27]. However, generally, the heterogeneous electron transfer rate should increase and the overpotential should decrease as the interaction between the catalyst and the substrate is increased.…”

Stabilized a-Ni(OH) 2 nanoparticle modified fluorine doped tin oxide (FTO) electrodes were shown to be excellent glucose amperometric FIA sensors exhibiting high specific sensitivity (446 mA mM À1 cm À2 ), low limit of detection (3 mM) and high analytical frequency (128 analyses/hour). The electrodes were constituted by~20 nm nanoparticles and the limit of detection was only slightly improved in hydrodynamic as compared to diffusional conditions reflecting the enhanced surface area and the moderate heterogeneous electron transfer rates at the nanostructured aNi(OH) 2 /solution interface.

“…The PA-PADPP covered electrode was rinsed with chloroform to remove the excess monomer before 10 mL of the ODNprobe (1.35 nmol) was pipetted over the electrodes surface. After measurement by cyclic voltammetry in LiClO 4 with ACN as solvent, the electrode was kept at room temperature for 1 hour. The resulting ODN-probed PA-PADPP/ITO bioelectrode was thoroughly washed with a phosphate buffer solution (PBS) of pH 7.4 to rinse off any loosely bound ODN-probe from the electrode.…”

“…Among these materials, metalloporphyrins have been used as attractive agents for electrode modification and are useful in photoelectrochemical processes due to their strong light absorption in the visible to near-ultraviolet region [2,3]. Moreover, modifying electrode surfaces with electropolymerized porphyrin films have been studied because of the ease of film formation and their potential in catalysis and sensor applications [4,5]. An attractive future direction in porphyrin research would be to apply their characteristics for the production of electricity or fuels [1].…”

The preparation and electropolymerization of a new porphyrin monomer with an amino group connecting the porphyrin core and aniline unit were studied. Cyclic voltammetry, FTIR spectroscopy, and a tandem quadrupole/time of flight mass spectrometry with matrix-assisted laser desorption/ionization source (MALDI-QqTOF) were used for the characterization of poly(5-(4'-aminophenylamino)-10,20-diphenylporphyrin) (PAPADPP). The PAPADPP formed a smooth layer on the Indium tin oxide (ITO) electrode and grew perpendicular to the electrode surface. An oligonucleotide (ODN)-probe was physisorbed onto the PAPADPP film and tested for hybridization with complementary and noncomplementary ODN segments. Biological recognition was monitored by comparison of the electrochemical signals (cyclic voltammogram) from single and double strand state oligonucleotides. The morphology of the physisorbed ODN-probe and its hybridization were observed on ITO electrodes using AFM and SEM.
