Cholesterol oxidase modified gold electrodes as bioanalytical devices

Cholesterol oxidase (ChOx) has been immobilized by direct adsorption on gold electrodes. The resulting ChOx monolayers have been characterized using atomic force microscopy (AFM) under liquid conditions and quartz crystal microbalance (QCM) techniques. The immobilized enzyme retains its catalytic activity, thus spatially resolved mapping of enzymatic activity has been carried out using scanning electrochemical microscopy (SECM). The replacement, in the enzymatic reaction, of the natural electron acceptor (O2) by an artificial mediator has been also evaluated, in particular, hydroxymethylferrocene (HMF), thionin, nile blue and azure A, have been studied as electron acceptors for reduced ChOx. In addition, the influence of the low cholesterol solubility on the experimental conditions using redox mediators was also discussed. Finally, the response of the enzymatic electrode to varying cholesterol concentrations has been obtained by measuring directly the H2O2 generated in the enzymatic reaction. Cholesterol can be determined amperometrically at +0.5 V (versus SSCE) with a detection limit of 60 muM and a sensitivity of 0.13 muA mM-1.

Effects of ferrocenyl 4-(Imino)-1,4-dihydroquinolines on xenopus laevis prophase i-arrested oocytes: Survival and hormonal-induced m-phase entry

Xenopus oocytes were used as cellular and molecular sentinels to assess the effects of a new class of organometallic compounds called ferrocenyl dihydroquinolines that have been developed as potential anti-cancer agents. One ferrocenyl dihydroquinoline compound exerted deleterious effects on oocyte survival after 48 h of incubation at 100 muM. Two ferrocenyl dihydroquinoline compounds had an inhibitory effect on the resumption of progesterone induced oocyte meiosis, compared to controls without ferrocenyl groups. In these inhibited oocytes, no MPF (Cdk1/cyclin B) activity was detected by western blot analysis as shown by the lack of phosphorylation of histone H3. The dephosphorylation of the inhibitory Y15 residue of Cdk1occurred but cyclin B was degraded. Moreover, two apoptotic death markers, the active caspase 3 and the phosphorylated histone H2, were detected. Only 7-chloro-1-ferrocenylmethyl-4-(phenylylimino)-1,4-dihydroquinoline (8) did not show any toxicity and allowed the assembly of a histologically normal metaphase II meiotic spindle while inhibiting the proliferation of cancer cell lines with a low IC50, suggesting that this compound appears suitable as an antimitotic agent.

Parylene C coated microelectrodes for scanning electrochemical microscopy

Herein, we present a simple microelectrode preparation methodology consisting in coating a platinum wire or a carbon fiber with a thin insulating Parylene C film (e.g. 1-10 mum), to produce SECM probes with a small and constant probe RG (i.e. ratio between the radius of the insulating sheath and the radius of the active electrode area). After exposition of a fresh active electrode area by blade cutting, a disc shaped electrode is obtained thanks to a protective hot mounting wax layer that avoids Parylene C coating deformation and is easily removed with acetone. Stiffness and straightness of the probe can be tuned by modifying the Parylene C coating thickness and the length of the carbon fiber or platinum wire. This simple electrode preparation method is highly reproducible (c.a. > 90%). The prepared Parylene C coated microelectrodes were characterized by optical microscopy, cyclic voltammetry, scanning electrochemical microscopy (SECM) approach curves and finally applied to SECM imaging of Pt band structures in contact-less and contact mode.

Time-dependent behavior of cation transport through cellulose acetate-cationic polyelectrolyte membranes

Cation transport through a cellulose acetate-poly(N,N-dimethylaminoethyl methacrylate) membrane (CA:PDMAEMA) was studied with scanning electrochemical microscope (SECM) and the thickness increase of the membrane was monitored with ellipsometry. Upon addition of the polyelectrolyte PDMAEMA, the permeability of the probe cation (ferrocenium methanol, FcMeOH) was increased as much as 40-fold. Soaking membranes in an electrolyte solution doubled the permeability in plain CA membranes, whereas for PDMAEMA containing membranes the opposite was observed and the permeability was reduced by 20?40%. This time-dependent behavior is shown to be a result of the presence of PDMAEMA within the membrane matrix, thus providing an interesting platform for controllable membrane permeability.

Responsive Gel-like Supramolecular Network Based on Pillar[6]arene-Ferrocenium Recognition Motifs in Polymeric Matrix

A dual-responsive supramolecular network based on pillar[6]arene-ferrocenium redox-controllable recognition motifs in polymeric backbones is constructed with a ferrocenium-functionalized copolymer and a pillar[6]arene copolymer, in which the first example of pillar[6]arene-functionalized copolymer was synthesized through the reversible addition/fragmentation chain-transfer copolymerization of an acrylate-functionalized pillar[6]arene and methyl acrylate. The resulting supramolecular network exhibits dramatically increased viscosity than the non-cross-linked mixtures and demonstrates a gel-like behavior on macroscale with a transient-network behavior revealed by rheology study. Furthermore, the viscoelastic properties of such supramolecular network can be easily controlled by different external stimuli including redox stimulus and competing host/guest reagents.

Improvement of the corrosion resistance of biomedical zr-ti alloys using a thermal oxidation treatment

Binary Zr-Ti alloys spontaneously develop a tenacious and compact oxide layer when their fresh surface is exposed either to air or to aqueous environments. Electrochemical impedance spectroscopy (EIS) analysis of Zr-45Ti, Zr-25Ti, and Zr-5Ti exposed to simulated physiological solutions at 37 C evidences the formation of a non-sealing bilayer oxide film that accounts for the corrosion resistance of the materials. Unfortunately, these oxide layers may undergo breakdown and stable pitting corrosion regimes at anodic potentials within the range of those experienced in the human body under stress and surgical conditions. Improved corrosion resistance has been achieved by prior treatment of these alloys using thermal oxidation in air. EIS was employed to measure the corrosion resistance of the Zr-Ti alloys in simulated physiological solutions of a wide pH range (namely 3 ? pH ? 8) at 37 C, and the best results were obtained for the alloys pre-treated at 500 C. The formation of the passivating oxide layers in simulated physiological solution was monitored in situ using scanning electrochemical microscopy (SECM), finding a transition from an electrochemically active surface, characteristic of the bare metal, to the heterogeneous formation of oxide layers behaving as insulating surfaces towards electron transfer reactions.

Semiconductor Property and Corrosion Behavior of Passive Film Formed on Steel with Zinc Coating in 5% NaCl Solution

The initial stage of corrosion behavior and the semiconductor property of a passive film formed on steel with zinc coating were investigated in 5?wt.% NaCl solution using scanning electrochemical microscopy (SECM), electrochemical impedance spectroscopy (EIS), potential-capacitance measurement and the Mott?Schottky analysis method. The SECM test results reveal that the Faradic currents on the tip of the ultramicro electrode decreased with the extension of immersion time, suggesting that the coating was slowly degrading, and the water and ions gradually permeated into the coating. The tip current remained stable without obvious bursting and swelling, which revealed that no blister occurred inside the coating. EIS results also support the above conclusion, especially for long-term immersion. The potential-capacitance and Mott?Schottky analysis show that the water and ions gradually entered into the coating during the immersion process, while at the same time the coating showed the characteristics of n-type semiconductor. As the time elapsed, the capacitance value decreased and the thickness of the space charge layer declined. The decrease in the slope of the Mott?Schottky curves suggested the simultaneous increase of the carrier density, and the coating was degrading. SEM observation also exhibits an obvious coating degradation after immersion compared with the previous coating without immersion in solution.
