Deciphering the Magnitude of Current Steps in Electrochemical Blocking Collision Experiments and Its Implications

The magnitude of the current steps due to blocking collisions is shown to be proportional to the square of the particle size, the concentration of the redox mediator, and inversely proportional to the size of the indicator electrode. A theoretical model and a simple analytical expression have been developed that allow for estimation of the average value of the current step magnitude in blocking collisions. Thus, it is now possible to directly relate the size of the analyte to the size of the average current step without worrying about the edge effect. It is proposed that by using the developed model and equations one could monitor the state of analyte species in solution, i.e., whether it is aggregated or not.

Selectivity mechanisms at self-assembled monolayers on gold: Implications in redox recycling amplification systems

Redox recycling systems enable marked improvement of electrochemical detection capabilities. Enhanced sensitivity is achieved by employing a sacrificial redox species that recycles the analyte back to its original oxidation state through a catalytic homogeneous electron transfer. Repetition of the cycle leads to multiple heterogeneous electron transfer events for each analyte molecule, serving to enhance the transduced signal. The success of redox recycling is intimately linked to the selectivity of heterogeneous electron transfer: the analyte should undergo a fast reaction while the sacrificial species should ideally be excluded from contributing directly to the current. This requirement stems from the relationship between selectivity and detection limit in that the direct heterogeneous electrolysis of the sacrificial additive can increase the background current which can degrade detection capabilities. Earlier work has shown that electrodes with suitable selectivity can be constructed using alkanethiolate monomolecular films on gold, with various ferrocenes (FcX) serving as a model analyte and ferrocyanide (Fe (CN)64 -) acting as the recycling agent [A.J. Bergren, M.D. Porter, J. Electroanal. Chem. 585 (2005) 172, A.J. Bergren, M.D. Porter, J. Electroanal. Chem. 591 (2006) 189, P.T. Radford, M. French, S. E. Creager, Anal. Chem. 71 (1999) 5101, P.T. Radford, S.E. Creager, Anal. Chim. Acta 449 (2001) 199, S.E. Creager, P.T. Radford, J. Electroanal. Chem. 500 (2001) 21]. The work herein investigates the origins of the selectivity for this system by analysis of the different pathways (e.g., electron transfer kinetics, size-exclusion, and partitioning) that can suppress the heterogeneous electrolysis of Fe (CN)64 -, while maintaining that for FcX at a rapid level. Comparisons of experimental data to expectations derived from model assessments are used to evaluate the relative importance of each possibility. The properties (i.e., size and hydrophobicity) of several FcX molecules and Fe (CN)64 – are also examined to provide additional insight into the processes that are important in creating a potent redox recycling system. These results show how the inherent differences in the heterogeneous electron transfer reaction rates can dictate the kinetic selectivity of the system. These findings indicate that partitioning augments the kinetic selection for the FcX / Fe (CN)64 – system, leading to the high level of observed selectivity.

Electrochemical activity of new ferrocene-labelled PNA monomers to be applied for DNA detection: Effects of the molecular structure and of the solvent

PNA oligomers are promising candidates as DNA probes on account of their very high DNA binding power, but they generally require an appropriate electrochemically or spectroscopically active marker. This paper describes the systematic electrochemical characterization of two newly synthesized PNA monomers, derivatised with one or three active ferrocene groups, and of their precursors. Our monomers show high electrochemical activity in spite of their bulkiness; moreover, the systematicity of our investigation affords an interesting analysis of the role of the molecular structure, the degree of functionalization and the working solvent on the electrochemical activity of the organometallic site.

Simultaneous noncontact topography and electrochemical imaging by SECM/SICM featuring ion current feedback regulation

We described a hybrid system of scanning electrochemical microscopy (SECM) and scanning ion conductance microscopy (SICM) with ion current feedback nanopositioning control for simultaneous imaging of noncontact topography and spatial distribution of electrochemical species. A nanopipette/nanoring electrode probe provided submicrometer resolution of the electrochemical measurement on surfaces with complex topology. The SECM/SICM probe had an aperture radius of 220 nm. The inner and outer radii of the SECM Au nanoring electrode were 330 and 550 nm, respectively. Characterization of the probe was performed with scanning electron microscopy (SEM), cyclic voltammetry (CV), and approach curve measurements. SECM/SICM was applied to simultaneous imaging of topography and electrochemical responses of enzymes (horse radish peroxidase (HRP) and glucose oxidase (GOD)) and single live cells (A6 cells, superior cervical ganglion (SCG) cells, and cardiac myocytes). The measurements revealed the distribution of activity of the enzyme spots on uneven surfaces with submicrometer resolution. SECM/SICM acquired high resolution topographic images of cells together with the map of electrochemical signals. This combined technique was also applied to the evaluation of the permeation property of electroactive species through cellular membranes.

A novel chiral phosphino-phosphaferrocene: Its coordination behavior and application to palladium-catalyzed asymmetric allylic alkylation

The synthesis of a novel chiral phosphino-phosphaferrocene ligand is described. The ligand possesses two electronically distinctive donor moieties and behaves either as a monodentate (with a free phosphaferrocene) or a bidentate ligand depending on stoichiometry with a coordinating transition-metal center. In the palladium-catalyzed asymmetric allylic alkylation of 1,3-diphenyl-2-propenyl acetate, a clear correlation was observed between the enantioselectivity of the reaction and a Pd/phosphino-phosphaferrocene molar ratio. With a deficient amount (to the Pd) of the chiral ligand, the highest enantioselectivity (99% ee) was achieved.

Construction of multiple switchable sensors and logic gates based on carboxylated multi-walled carbon nanotubes/poly(N,N-diethylacrylamide)

In this work, binary hydrogel films based on carboxylated multi-walled carbon nanotubes/poly(N,N-diethylacrylamide) (c-MWCNTs/PDEA) were successfully polymerized and assembled on a glassy carbon (GC) electrode surface. The electroactive drug probes matrine and sophoridine in solution showed reversible thermal-, salt-, methanol-and pH-responsive switchable cyclic voltammetric (CV) behaviors at the film electrodes. The control experiments showed that the pH-responsive property of the system could be ascribed to the drug components of the solutions, whereas the thermal-, salt-and methanol-sensitive behaviors were attributed to the PDEA constituent of the films. The CV signals particularly, of matrine and sophoridine were significantly amplified by the electrocatalysis of c-MWCNTs in the films at 1.02 V and 0.91 V, respectively. Moreover, the addition of esterase, urease, ethyl butyrate, and urea to the solution also changed the pH of the system, and produced similar CV peaks as with dilution by HCl or NaOH. Based on these experiments, a 6-input/5-output logic gate system and 2-to-1 encoder were successfully constructed. The present system may lead to the development of novel types of molecular computing systems.

Electrochemical monitoring of reactive oxygen/nitrogen species and redox balance in living cells

Levels of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cells and cell redox balance are of great interest in live cells as they are correlated to several pathological and physiological conditions of living cells. ROS and RNS detection is limited due to their spatially restricted abundance: they are usually located in sub-cellular areas (e.g., in specific organelles) at low concentration. In this work, we will review and highlight the electrochemical approach to this bio-analytical issue. Combining electrochemical methods and miniaturization strategies, specific, highly sensitive, time, and spatially resolved measurements of cellular oxidative stress and redox balance analysis are possible. [Figure not available: see fulltext.].

IR spectral and X-ray single crystal study of hydrogen bonds and structure of nonamethylferrocenyl- and ferrocenylcarbinols in the solid state

The influence of different substituents in the Cp-ring and at the carbinol C atm on the character and stability of H bonds in crystals of FcCHROH and 9FcCHROH, Fc = C5H5FeC5H4; 9Fc = C5Me5FeC5Me4, (R = H, CH3, C6H5, C6F5) was studied by IR spectroscopy specifically in the nu(OH) region.In the crystals, molecules associate predominantly via intermolecular OH…O bonds.However, in some of the 9FcCHROH complexes, the intermolecular O-H…?(Cp) H bonds are also formed.The major type of self-association in compounds with R = Mes is OH…?(Mes) H-bonding.It was found from the X-ray structural data for the 9FcCHMesOH that the Mes plane is almost perpendicular to each Cp ring plane.No intermolecular OH…O bonds are formed because of intramolecular shielding of the OH group.The stability of the intermolecular hydrogen bonds is determined by steric rather than electronic factors, the most stable intermolecular hydrogen bonds being formed in the case of primary carbinols.

A Feedback Control Approach to Organic Drug Infusions Using Electrochemical Measurement

Goal: Target-controlled infusion of anesthesia is a closed-loop automated drug delivery method with a computer-aided control. Our goal is to design and test an automated drug infusion platform for propofol delivery in total intravenous anesthesia (TIVA) administration. Methods: In the proposed method, a dilution chamber with first-order exponential decay characteristics was used to model the pharmacodynamics decay of a drug. The dilution chamber was connected to a flow system through an electrochemical cell containing an organic film-coated glassy carbon electrode as working electrode. To set up the feedback-controlled delivery platform and optimize its parameters, ferrocene methanol was used as a proxy of the propofol. The output signal of the sensor was connected to a PI controller, which prompted a syringe pump for feedback-controlled drug infusion. Results: The result is a bench-top drug infusion platform to automate the delivery of a propofol based on the measurement of concentration with an organic film-coated voltammetric sensor. Conclusion: To evaluate the performance characteristics of the infusion platform, the propofol concentration in the dilution chamber was monitored with the organic film-coated glassy carbon electrode and the difference between the set and measured concentrations was assessed. The feasibility of measurement-based feedback-controlled propofol delivery is demonstrated and confirmed. Significance: This platform will contribute to high-performance TIVA application of intravenous propofol anesthesia.
