“…However, even though the chromatographic methods permit to effectively determine dopamine in the presence of many interfering compounds, it is ecologically unfavourable due to the use of high amounts of solvents. In addition, these methods require laborious steps, relatively expensive equipment and trained professionals .…”

In this manuscript, a novel photoelectroanalytical sensor for detection of dopamine based on anatase TiO2 nanoparticles sensitized with copper tetrasulfonated phthalocyanine (CuTsPc/TiO2) was developed. The CuTsPc/TiO2 photoelectroanalytical sensor shows high anodic photocurrent under visible light emitting diode irradiation in comparison to pure anatase TiO2 nanoparticles. The CuTsPc/TiO2 composite shows a photocurrent about 2.5‐fold higher than those of pure TiO2 nanoparticles or CuTsPc modified electrode. The CuTsPc/TiO2 composite shows a low charge transfer resistance in comparison to its individual components as well as the impedance circle radius decreases significantly under UV light illumination. Under optimized conditions, the photoelectroanalytical sensor shows a linear response range from 4 up to 810 µmol L−1 with a sensitivity of 3.0 nA L µmol−1 and limit of detection of 0.5 µmol L−1 for the detection of dopamine. The photoelectrochemical sensor shows high photocurrent to dopamine in comparison to foreign species such as ascorbic acid, uric acid, glucose, K+, Na+, and Cl−.

“…oxydans is significantly higher than that of Poly(GMA-co-MTM)/ G. oxydans, it was obtained slightly less sensitive compared with the studies reported in the literature [27,28]. In contrast, the working electrodes showed a wide linear range and high stability among the glycerol sensors [23][24][25][26][27][28][29][30][31][32]. It is thought that these results were very much dependent on the use of Poly(GMA-co-MTM) as a matrix for G. oxydans whole cells.…”

The use of copper−metal−organic framework (Cu-MOF) as a versatile electrocatalyst signifies a transformative breakthrough with profound implications for sustainable energy and advanced analytical capabilities in the biodiesel industry. We present an economically efficient, Cu-MOF microneedle decorated nickel foam (NF)-based electrochemical sensor for detecting glycerol (Gly) in biodiesel and as an electrocatalyst for glycerol fuel cells. Herein, we utilized a simple and efficient solvothermal approach to synthesize Cu-MOF, then conducted a comprehensive analysis to study the material's morphological, structural, and functional groups using different material characterization techniques like transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transmission infrared spectroscopy (FTIR), etc. The Cu-MOF-modified NF electrocatalyst shows a remarkable current density of 690 mA/cm 2 , and the sensor exhibits exceptional selectivity, sensitivity, and a low limit of detection (LOD) of 0.172 μM. Cu-MOF/NF is highly selective over other interfering species (methanol, Na + , K + , Ca 2+ , Mg 2+ cations, and phosphates) and in biodiesel samples with an outstanding recovery percentage of ∼101%. The microneedle structure of Cu-MOF plays a pivotal role in augmenting catalytic activity, providing increased surface area and providing active sites for electrochemical reactions. This is the first report on the utilization of Cu-MOF as bifunctional electrocatalysts, exploring their applications in glycerol fuel cells for sustainable energy generation as well as their role in electrochemical sensing for the accurate quantification of glycerol in biodiesel samples.
