Article
Full-text available
UV/Vis absorption spectroelectrochemistry (SEC) is a multi-response technique that has been commonly used for the characterization of materials and the study of reaction mechanisms. However, it has been scarcely used for quantitative purposes. SEC allows us to obtain two analytical signals simultaneously, yielding a dual sensor in just one experime...
Article
In this work, UV/Vis spectroelectrochemistry (SEC), in a thin-layer regime and parallel configuration, is selected to solve a complex mixture that contains dopamine (DA), ascorbic acid (AA) and uric acid (UA). These molecules, like many other biological compounds, are assuming a highly important place in analytical and biomedical fields due to the...
Article
Spectroelectrochemistry (SEC) is a set of techniques with many advantages in the study and characterization of materials. Although SEC has not yet been widely used to study quantum dots (QDs), the information extracted from SEC experiments about these nanostructures is very useful. Most of the works that use SEC to study QDs are high‐quality pieces...
Article
Spectroelectrochemistry (SEC) has been used for more than 50 years, but this set of techniques has not been widely used for quantitative analysis. For many years, no commercial instruments were available, which made very difficult to spread the use of SEC. Nowadays, only the creativity of the researchers is required to exploit the capabilities of S...

A flexible electrode system entirely constituted by single-walled carbon nanotubes (SWCNTs) has been proposed as the sensor platform for β-nicotinamide adenine dinucleotide (NADH) detection. The performance of the device, in terms of potential at which the electrochemical process takes place, significantly improves by electrochemical functionalizat...
Article
The amount of qualitative and quantitative information provided by a UV–vis absorption spectroelectrochemistry (SEC) experiment is sometimes wasted. However, almost all electrochemical and spectroscopic data can provide valuable information. In this spirit, the main objective proposed in this work is the quantitative resolution of catechol/dopamine...
Article
A spectroelectrochemistry device capable of studying different regions of an electrode surface in a strictly simultaneous way is presented in this work. It is based on two reflection probes placed in a near-normal arrangement with respect to a working electrode surface, part of which has been deliberately modified. As expected, the electrochemical...
Article
UV–Vis absorption thin-layer spectroelectrochemistry greatly contributes to the assessment of parameters of electron-transfer reactions by providing electrochemical and spectroscopic information obtained simultaneously in a confined space around the working electrode. In this work we present an ingenious modification of a spectroelectrochemistry de...
Article
The research field of real samples is pretty much complicated than the study of other systems. However, the inherent advantages of UV−vis absorption spectroelectrochemistry should overcome some difficulties related to direct measurements in complex matrices. For this reason, a singular spectroelectrochemistry device has been fabricated and validate...

Spectroelectrochemistry (SEC) is a multi-response technique that allows the simultaneous observation of a physico-chemical phenomenon from different points of view. In electrochemistry, although most experiments are conducted under semi-infinite diffusion conditions, the performance of analysis under thin-layer conditions, for example a small volum...
Article
A versatile and low-cost methodology for fabricating free-standing carbon nanotubes (CNT) electrodes for electrochemical and spectroelectrochemical applications is described. The uniformity, flexibility and resistance to bending of these films make them one of the most interesting membranes in a wide range of applications. CNT electrodes were chara...
Presentation
Spectroelectrochemistry (SEC) is a very valuable technique both in characterization of materials and the study of reaction mechanism. Here we present the combination of UV/Vis SEC with different chemometric tools to resolve complex mixtures of different biomolecules with a high interference level both in the electrochemical and the spectroscopic si...
Presentation
Spectroelectrochemistry (SEC) is a very valuable technique both in characterization of materials and the study of reaction mechanism. In time-resolved UV/Vis absorption SEC, absorbance values depend on the wavelength, the potential/time and the concentration of the analyte. Therefore, this is a trilinear technique that is very useful in quantitativ...
Article
The development of a new device based on the use of UV-vis bare optical fibers in long optical path length configuration and the measurement of the Raman response in normal arrangement allows us to perform UV-vis and Raman spectroelectrochemistry simultaneously in a single experiment. To the best of our knowledge, this is the first time that a spec...

La espectroelectroquímica es una poderosa técnica que nos permite obtener, simultáneamente, la evolución electroquímica y espectroscópica de una reacción electroquímica. La posibilidad de encontrar dos compuestos químicos que presenten el mismo potencial de oxidación e idéntico espectro de absorción UV-vis es francamente difícil. Este hecho particu...
Article
Optically transparent electrodes (OTEs) are needed for a wide range of applications such as solar cells, printable electronics, touch screens, light emitting diodes or flexible displays. Furthermore, OTEs are required for normal transmission spectroelectrochemistry measurements to obtain simultaneously electrochemical and spectroscopic responses. T...
Article
A number of renewable energy systems require an understanding and correlation of material properties and (photo)electrochemical activity on the micro to nanoscale. Among these, conducting polymer electrodes continue to be important materials. In this contribution, an ultrasensitive scanning electrochemical cell microscopy (SECCM) platform is used t...

A new thin-layer optical fiber spectroelectrochemistry cell in parallel configuration has been developed with very promising results. A three-electrode system has been fabricated on a polyethylene terephthalate s upport us ing our pres s -trans fer methodology1. A very small volume of solution (around 30 μL) is needed to perform the characterizatio...

The use of single walled carbon nanotubes (SWCNTs) networks as material for electrodes is highly promising for electrochemical applications1. Meanwhile, spectroelectrochemistry is an in-situ auto-validated multi-response technique that studies the spectroscopic evolution of an electrochemical process. Taking as reference these two topics, the main...
Article
A really easy method to transfer commercial single-walled carbon nanotubes (SWCNTs) to different substrates is proposed. In this paper, a homogeneous transference of SWCNTs films to non-conductor and transparent supports such as polyethylene terephthalate, glass and quartz, and to conductor supports such as indium tin oxide, aluminium, highly order...
Article
A new long-optical-pathway spectroelectrochemical cell for absorptometric measurements in the UV-Vis region was developed. This cell consists of two optical fibers brought face to face and fixed on the working electrode support. As a proof of concept, the spectroelectrochemical cell was applied to the determination of catechol using a press-transfe...
Article
A novel single-walled carbon nanotubes press-transfer electrodes (SW-PTEs) for microfluidic sensing is proposed. In this approach, carbon nanotubes are press-transferred on poly-methyl-methacrylate (PMMA) substrates and easily coupled to microfluidic chips and acting as the exclusive transducer in the electrochemical sensing. The detector design co...
Article
A simple method for the fabrication of optically transparent electrodes (OTE) from commercial single-walled carbon nanotubes (SWCNT) is presented. We disperse SWCNT in organic solvents, avoiding surfactants. Films obtained by filtering are transferred to non-conductive polymer substrates only by pressure, avoiding the chemical removing of the filte...
Article
In this paper, we report the preparation of highly stable gold nanoparticles/poly(3,4-ethylendioxythiophene) nanocomposites by a one-pot chemical route in aqueous medium without surfactants to increase the solubility of the monomer (3,4-ethylendioxythiophene, EDOT) or to stabilize gold nanoparticles (Au NPs). The generation of the nanocomposite was...
