Summary: Cyclic voltammetry and differential pulse voltammetry were used to study the behavior of methylene blue at a mercury meniscus-modified silver solid amalgam electrode. Electrochemical impedance spectroscopy was used for verification and comparison. It was found that the reduction signal of methylene blue was significantly higher at the DNA-modified silver amalgam electrode compared to the unmodified electrode, which correlated with changes in charge transfer resistance. Optimized parameters were determined for further biosensor development and applications.

Summary: In this study, complex characterization and comparison of as-grown and chemical-mechanical polished ultra-thin boron doped diamond electrodes were performed. The results showed that chemical-mechanical polishing reduced the roughness of the electrode surface to below 2 nm and improved the precision of electron backscatter diffraction. X-ray photoelectron spectroscopy confirmed an increase in boron content on the surface of highly doped boron doped diamond electrodes. Additionally, chemical-mechanical polished BDD electrodes exhibited a uniform distribution of conductivity, faster heterogeneous electron transfer kinetics, and higher double layer capacitance compared to as-grown electrodes. The electroanalytical performance of chemical-mechanical polished BDD electrodes for dopamine detection was superior.

Summary: This work presents a novel three-electrode plastic sensor chip for the detection of trace Hg(II) using anodic stripping voltammetry. The chip is manufactured by injection moulding, which is an eco-friendly and sustainable method. It consists of three carbon-based electrodes embedded in a plastic holder, and the reference electrode is coated with Ag using e-beam evaporation. By analyzing the sample spiked with Au(III), gold nanoparticles are formed on the working electrode, and Hg(II) co-deposits with the gold nanoparticles to form an Au(Hg) amalgam. The accumulated Hg(II) is then stripped off the electrode and measured using an anodic square wave potential scan. The sensor shows a limit of detection of 0.4 μg/L for Hg(II) and a repeatability of 5.3% at the 20 μg/L level of Hg(III) (n = 10). It is successfully applied to various samples with recoveries ranging from 98% to 107%.

Summary: Two new Fe(II) Metal-Organic Frameworks (MOFs), namely 3D-Fe-MOF and 2D-Fe-MOF, were successfully synthesized and characterized by adjusting the reaction conditions to achieve the optimal degree of deprotonation of the bridging ligand. Both MOFs showed stability in water and had the ability to sorb glucose, although the sorption capacity was negligible. A 3D-Fe-MOF modified graphite paste sensor (GPE) was fabricated for non-enzymatic glucose detection in aqueous solution, and preliminary results were discussed using differential pulse voltammetry.

Summary: A thorough study has been conducted on the conversion of sp3 to sp2 carbon in undoped and boron-doped diamond thin layers. It was found that the incorporation of boron atoms increased the infrared optical absorption and reduced the energy fluence required for carbon conversion. Raman spectroscopy was used to identify carbon conversion stages and optimize parameters for other infrared laser sources. Electrochemical measurements showed significant changes in parameters after the conversion of 10% of sp3 carbon to sp2 carbon.
