The different techniques nowadays applied in life sciences may be considered as individual instruments in a symphony orchestra, each providing different valuable information. Fundamental questions are addressed regarding biomolecules, biomolecule-modified surfaces, live cells and complex biological functions such as cell signaling cascades, influences on cell proliferation, gene expression and cell death. Techniques such as optical microscopy, electrophoresis, chromatographic techniques bulk or on-chip electrochemical measurements and spectroscopic techniques are among the approaches providing bulk information usually averaging over a large number of biological entities. However, for most of the listed techniques either modification or complexing agents may be necessary and/or the obtained information cannot be correlated to structural changes. Fluorescence-based and high-resolution optical techniques provide spatially resolved information down to individual molecules (e.g., single molecule fluorescence) but usually require labeling steps.1 Scanning probe microscopy (SPM) techniques such as atomic force microscopy (AFM),2 scanning electrochemical microscopy (SECM)3 and scanning ion conductance microscopy (SICM)4 yield valuable information when investigating biological samples in respect to topographical and structural analysis of, for example, cells, yet some of them lack chemical and molecular specificity. In particular electrochemical methods5,6 play a dominant role in studying signaling processes as many transmitter molecules are either electroactive molecules (e.g., catecholamines)7 or can be selectively determined using biosensors.8 Ideally, the detection of specific constituents and the response to stimulation and/or changes of the biological sample should be obtained in a temporally and spatially resolved manner. SECM, as introduced by Bard and co-workers,9 is an attractive scanning probe technique for life sciences and related research areas, which was already demonstrated by early investigations on biological samples10,11 and first enzyme activityrelated investigations presented in 1992.12 Since then, SECM evolved into an increasingly popular technique for studying biochemical and bio-related processes. Significant progress has been made over the years in instrumental developments, by introducing new imaging modes and establishing comprehensive theoretical models. While the early years of SECM were certainly shaped by the team of A. Bard and the research groups emerging from this nucleus, not much later research groups in Japan13-15 and Europe16-24 contributed to SECM research in the field of life sciences. In the early twenty-first century, SECM was improved in respect to resolution, introducing new imaging modalities and SECM research expanded to the investigation of DNA,25-27 cells,28,29 membranes30,31 and neurons.32 Returning to the metaphor of an orchestra, the musical development in allegro was not just limited to its leitmotif of SECM, but combinations with other scanning probe techniques such as AFM and SICM or optical techniques enriched the Symphony. Within this chapter an overview on SECM is provided along with the imaging modalities on biologically relevant applications in the life sciences and related research areas with selected examples. As this chapter cannot be comprehensive, the interested reader is directed further to the seminal book Scanning Electrochemical Microscopy.

Local electrochemical techniques such as scanning electrochemical microscopy, scanning vibrating electrode technique, local electrochemical impedance spectroscopy, scanning Kelvin probe technique, and scanning ion-selective electrode technique have gained significant attention in organic coating research. These techniques have enhanced our understanding of the fundamental processes of corrosion at defects and underneath coatings. Each of these techniques employ unique measurement strategy to provide important local information about coatings, their protective properties, defects, and failure mechanisms. In this brief review, the basic principles of these techniques and the nature of information that has been extracted from these techniques to study organic coatings are discussed.

We report the electroanalytical properties of an amperometric bioelectrode containing l-lactate oxidase (LOx) immobilized on glassy carbon electrode with a hydrogel film composed of laponite and different amounts of a novel bioinspired polycation obtained by copolymerization of 4-vinylbenzyl thymine (VBT) and 4-vinylbenzyl triethylammonium chloride (VBA) in a molar ratio 1:4, respectively. The electrochemical behavior of the redox couple probe [Fe(CN)6]3-/4- of these VBT-VBA bioelectrodes was compared with that observed for a bioelectrode containing the classical polycation polydiallyldimethylammonium chloride (PDDA). The best response was obtained for a bioelectrode containing a VBT-VBA/laponite mass ratio double than the cationic exchange capacity of the clay, demonstrating that under this condition the polycation induces an optimal microenvironment in the interlamellar space of the clay, both for the position and the functionality of LOx. The VBT-VBA bioelectrode displayed a very high sensitivity (7.2 ± 0.2) × 102 muA mM-1 cm-2, a short time response (<5 s), a wide linear response range (e.g. 0.01-1.0 mM of l-lactate) and an excellent stability over a storage period of 60 days, when sensing l-lactate. The analytical response of the bioelectrode was tested in real food samples, e.g. milk, white wine, and beer, as well as during milk fermentation at 37 C. No effect of molecular interferences in the food matrices was detected, and the quantification of l-lactate was in complete agreement with standard assays reported values. Current results indicate that polycations containing the multifunctional green monomer VBT have high potential for their use in hydrogel film formation producing more responsive and stable electrochemical biosensors. Improvement of the amperometric response to l-lactate by using a cationic bioinspired thymine polycation in a bioelectrode with immobilized lactate oxidase Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.

Hyphenated techniques have become an important tool in modern analytical research. Among detection techniques, mass spectrometry (MS) plays a dominant role, but efficient analyte separation prior to MS detection is usually desirable, as it provides the basis for reliable qualitative and quantitative determination. However, electrochemical methods offer very versatile approaches for selective sample pretreatment or analyte conversion. This review summarizes recent instrumental analytical developments, which resulted in a special kind of a hyphenated system: electrochemistry-capillary electrophoresis-MS (EC-CE-MS). We discuss the analytical characteristics of this approach and compare them with those of other techniques coupling EC with separation techniques and MS.

A novel, simple and label-free multianalyte immunoassay system is presented here by integrating arrayed electrodes on a silicon chip via MEMS. The chip is consisted of six Au disk electrodes, an Au counter electrode and an Ag/AgCl reference electrode. Semi-insulating poly(o-phenylenediamine) (PoPD) was utilized to co-polymerize and immobilize antibodies at the arrayed Au electrodes, and wider linear detection range was obtained than those prepared with completely insulating PoPD. Electrochemical cyclic voltammogram (CV), AC impedance spectroscopy, AFM and fluorescence microscopy were employed to characterize the system. The arrayed electrodes offered exact control of deposition position via electrochemical operation, allowing selectively immobilization of different antibodies at desired positions on a single chip. Specific recognition of antibody (Ab) to corresponding antigen (An) was quantitatively monitored by cyclic voltammograms in the presence of electrochemical redox probe, ferrocene methanol. The proposed immunoassay chips showed sensitive response to three liver fibrosis markers, hyaluronic acid (HA), collagen type IV (IV-C) and lamin (LN) at ng/mL level simultaneously and specifically in a tiny amount of volume, usually 50 muL. The results obtained via chips were well consistent with those obtained by commercial radio immunoassays (RIA).

This work reports the successful application of bamboo-like multiwalled carbon nanotubes (bCNT) non-covalently functionalized with calf-thymus double stranded DNA (dsDNA) as a robust platform (bCNT-dsDNA) to build electrochemical biosensors. The “model system” proposed here as a proof of concept was an enzymatic biosensor devoted to glucose quantification obtained by layer-by-layer self-assemby of polydiallyldimethylammonium (PDDA) and glucose oxidase (GOx) at glassy carbon electrodes (GCE) modified with bCNT-dsDNA (GCE/bCNT-dsDNA/(PDDA/GOx)n). The influence of GOx and PDDA assembling conditions and the effect of the number of PDDA/GOx bilayers (n) on the performance of the resulting biosensor is critically discussed. The supramolecular architecture was characterized by electrochemical impedance spectroscopy from the charge transfer resistance of quinone/hydroquinone and potassium ferrocyanide/potassium ferricyanide; by cyclic voltammetry from the surface concentration of GOx using ferrocene methanol as enzyme regenerator; by amperometry from the response of the enzymatically generated hydrogen peroxide; and by surface plasmon resonance from the changes in the plasmon resonance angle. The analytical parameters obtained with GCE/bCNT-dsDNA/(PDDA/GOx)3 for the amperometric quantification of glucose at 0.700 V were: sensitivity of (265 ± 7) muA mM-1 cm-2, linear range between 0.25 and 2.50 × 10-3 M, detection limit of 50 muM, repeatability of 3.6% (n = 10), and negligible interference from maltose, galactose, fructose and manose. The biosensor was successfully used for the sensitive quantification of glucose in beverages and a medicine sample.

Moessbauer and NMR spectra are reported for ferrocenyl (Fc) carbenium ions, FcCH2+ (III+) and FcC+Me2 (II+) in frozen acidic media. 1H-NMR spectra showed no evidence of Fe-H bonded species.Moessbauer parameters for II+ were identical within experimental error to those obtained for the carbenium ion precursors and to ferrocene itself, whereas quadrupole splittings for III+ were significantly larger.The results for the latter species are interpreted in terms of stabilisation via orbital overlaps with the central iron atom.

Two types of transformations (the metal complex protonation and oxidation) have been revealed in the ferrocenylmethanol??2?2??? system (HX = HClO4, CF3COOH) by means of electronic spectroscopy. The efficiency of protonation has been determined from the intensity of the FcCH2 + carbocation absorption band (lambdamax = 600 nm); it depends on the acid strength and relative concentration as well as the solvent nature. Kinetics of ferrocenylmethanol oxidation in dioxane has been studied in the presence of trifluoroacetic acid. Two alternative reaction mechanisms have been proposed, differing in the coordination type of the reagents.

Covalent immobilization of glucose oxidase (GOx) on oxidized silicon (SiO2) surfaces is detailed in view of producing interfaces with a simple, controlled and reproducible procedure that could be used in bioanalytical applications as those based on SECM detection. The procedure is based first on the formation of an amino-terminated propyl layer on a SiO2 substrate followed by addition and cross-linking of a polyoxyethylene bis(diglycidylether) and GOx mixture. The epoxide groups of the cross-linker react with amino groups allowing both the cross-linking with the enzyme (reaction with the free amino groups of the lysine residues) and the covalent attachment of the enzyme layer on the amino groups bound to the surface. SECM in feedback mode analysis provides a characterization of the modified surface and the measurement of the enzymatic activity depending on the concentrations of glucose and mediator. Kinetics analysis indicates that GOx maintains a large enzymatic activity and that the active enzymes remain reachable after their incorporation in the layer with the advantages of a robust immobilization.
