Conformation-switched chemosensor for selective detection of Hg2+ in aqueous media

A conformation flexible chemosensor for selective detection of Hg2+ in aqueous media was achieved by incorporating two well-known rhodamine-6G dyes and a ferrocene group within one molecule. Distinguished from the monosubstituted ferrocene derivative which is previously reported a lack of interaction with Hg2+, the title compound was characteristic of two-armed bidendate binding unit. The Hg2+ sensing behavior can be switched via the conformation flexibility. The 1:1 sensor/Hg2+ binding mode was proposed and supported by the titration experiment and ESI mass spectrum. The fluorescent sensor can display a highly selective response of fluorescence enhancement toward Hg2+ and detect the parts per billion (ppb) level of Hg2+ in aqueous environment. Crown Copyright

Scanning electrochemical microscopy investigation of the rate of formation of a passivating TiO2 layer on a Ti G4 dental implant

Titanium and alloys with titanium as the major component are widely used for making biomedical implants, such as artificial dental roots. In our laboratory, we have studied the kinetics of the self-healing reaction of the TiO2 film that forms on the surface of such an implant. Amperometric SECM approach curves were recorded over the surface of a grade 4 titanium (Ti G4) dental implant sample at specific times after the metal surface had been exposed to an air-saturated buffer solution. A ferrocene methanol redox mediator and a platinum microelectrode tip (r = 12.5 mum) were used in the experiments. The effective rate coefficient (keff) values for the mediator regenerating surface reaction were estimated using Wittstock’s method from the approach curves recorded at different time points. Decreasing values of keff over time indicated an increasing rate of formation of the passivating TiO2 film.

Recent Advances in Applications of Voltammetric Sensors Modified with Ferrocene and Its Derivatives

This study is on current developments concerning ferrocene (FC) and its derivatives on the basis of electrochemical biosensors and sensors. The distinct physiochemical characteristics of FC have enabled the development of new sensor devices, specifically electrochemical sensors. Several articles have focused on the implementation of FC as an electrode constituent while discussing its electrochemical behavior. Furthermore, typical FC-design-based biosensors and sensors are considered as well as practical examples. The favorable design of FC-based biosensors and general sensors needs adequate control of their chemical and physical characteristics in addition to their surface immobilization and functionalization.

Anion interaction with ferrocene-functionalised cyclic and open-chain polyaza and aza-oxa cycloalkanes

A family of ferrocene-functionalised receptors of different topologies have been used as receptors for anions. The compounds have been designed to contain both amine nitrogen and ether oxygen atoms and comprises from monoaza to pentaaza derivatives both open-chain (L1, L2, L3) or cyclic (L4, L5) and having from one to five ferrocenyl groups. Solution studies directed to determine the protonation constants of L1, L2 and L3 have been carried out in water (0.1 mol dm3 KNO3, 25 C) and those of L4 and L5 in 1,4-dioxane-water (70:30 v/v, 0.1 mol dm-3 KNO3, 25 C). The protonation behaviour of the receptors can be explained taking into account electrostatic considerations. Speciation studies in the presence of phosphate have been carried out in water for L’, L2 and L3 and in dioxane-water for L4 and L5. Speciation studies have also been performed in the presence of ATP with L1, L2 and L3 in water. Selectivity of a mixture of receptors against a certain anion is discussed in terms of ternary diagrams. The shift of the redox potential of the ferrocenyl groups as a function of the pH has been studied. The difference between the oxidation potentials at basic and acidic pH has been determined experimentally and is compared with that theoretically predicted using an electrostatic model previously reported. The electrochemical shift in the presence of ATP and phosphate has been measured in water for L1, L2 and L3 and in the presence of phosphate and sulfate in 1,4-dioxane-water for L4 and L5 as a function of the pH. The electrochemical response found against those anions is quite poor with maximum cathodic shifts off. 30tO mV. The electrochemical response induced by HSO4 and H2PO4- has also been studied in acetonitrile solutions where a large cathodic shift for H2PO4- up to ca. 200 mV was found.

Nanostructured rough gold electrodes for the development of lactate oxidase-based biosensors

The design and characterization of a lactate biosensor using a nanostructured rough gold surface as a transducer is reported. The biosensor is developed by immobilization of lactate oxidase (LOx), on a rough gold electrode modified with a self-assembled monolayer of dithiobis-N-succinimidyl propionate (DTSP). This bifunctional reagent preserves the rough gold structure and allows further covalent immobilization of the enzyme through the terminal succinimidyl groups. The rough gold electrode is characterized using field emission scanning electron microscopy (FE-SEM) and atomic force microscopy (AFM). The preferential orientation and average crystallite size are obtained by X-ray diffraction (XRD). The resulting lactate oxidase monolayers are characterized by electrochemical impedance spectroscopy (EIS). This nanostructured transducer allows higher mediated electrocatalytic activity than polycrystalline ones. The biosensor response to increasing lactate concentrations, using hydroxymethylferrocene as a redox mediator in solution, is linear up to 1.2mM with a sensitivity of 1.49muAmM-1.

Direct high-resolution mapping of electrocatalytic activity of semi-two-dimensional catalysts with single-edge sensitivity

The catalytic activity of low-dimensional electrocatalysts is highly dependent on their local atomic structures, particularly those less-coordinated sites found at edges and corners; therefore, a direct probe of the electrocatalytic current at specified local sites with true nanoscopic resolution has become critically important. Despite the growing availability of operando imaging tools, to date it has not been possible to measure the electrocatalytic activities from individual material edges and directly correlate those with the local structural defects. Herein, we show the possibility of using feedback and generation/collection modes of operation of the scanning electrochemical microscope (SECM) to independently image the topography and local electrocatalytic activity with 15-nm spatial resolution. We employed this operando microscopy technique to map out the oxygen evolution activity of a semi-2D nickel oxide nanosheet. The improved resolution and sensitivity enables us to distinguish the higher activities of the materials? edges from that of the fully coordinated surfaces in operando. The combination of spatially resolved electrochemical information with state-of-the-art electron tomography, that unravels the 3D complexity of the edges, and ab initio calculations allows us to reveal the intricate coordination dependent activity along individual edges of the semi-2D material that is not achievable by other methods. The comparison of the simulated line scans to the experimental data suggests that the catalytic current density at the nanosheet edge is ?200 times higher than that at the NiO basal plane.

Investigation of a deoxyribozyme as a biofuel cell catalyst

We examined the ability of a previously identified peroxidase deoxyribozyme to be employed as a catalyst in biofuel cells, as a possible replacement for oxidoreductase proteins. We constructed a biocathode using a covalently linked version of the peroxidase deoxyribozyme-hemin complex and successfully paired it with a glucose dehydrogenase-modified bioanode for power production.
