Summary: This paper demonstrates the synthesis of a novel grass-like Pt-doped NiCo2O4 nanocomposite (GL Pt-doped NiCo2O4) and characterizes it using different techniques. The nanocomposite is used for the modification of screen-printed electrodes and shows suitable electrocatalytic behavior for the selective and sensitive detection of amlodipine in the presence of interfering ions and compounds. The differential pulse voltammetry method is used to achieve broad linearity and low detection limits for amlodipine. Moreover, the modified electrode shows acceptable recovery in drug and biological samples.

Summary: Two novel polymeric coordination compounds [Zn(2,6-ndc)(api)]n were synthesized with different solid-state architectures, PUC3 and PUC4, resulting from separation by different solvent mixtures. PUC3 has a four-fold interpenetrated 3D framework, while PUC4 is a porous framework formed by 2D corrugated layers. Both compounds were characterized using various techniques and demonstrated strong interaction with ascorbic acid (AA) and excellent detection limits.

Summary: Few layers of black phosphorus nanosheets (BPNS) were incorporated into glassy carbon electrodes (BPNS/GCE) for the electrochemical detection of uric acid (UA) using ultrasound-assisted liquid-phase exfoliation. The electrochemical response of BPNS/GCE showed significant increase in peak current magnitude and positive potential shift, which can be attributed to the larger specific surface area and good charge transfer ability of BPNS. Differential pulse voltammetry (DPV) was used to detect UA, and a linear response within the range of 1-1000 μM with a detection limit of 0.33 μM was achieved. This study reveals new applications of BP nanomaterials in electrochemical sensing and promotes further development in practical applications of two-dimensional nanomaterials.

Summary: Amperometry with ultramicroelectrodes is a routine technique for investigating neurotransmitter secretion by vesicular exocytosis at the single-cell level. The electrochemical detection may lead to acidification of the cell-electrode cleft, but a more general model taking into account buffer species movement and regeneration confirms the robustness of this technique. This model ensures that the pH within the cleft remains at its physiological value during usual exocytotic cell frequencies, regardless of the electrochemical detection of vesicular release.

Summary: In this study, four new fluorescent false neurotransmitters (FFN) probes were synthesized and their spectroscopic and electrochemical properties were investigated. The results showed that one of the probes (FFN122) had the optimal suitability for fluorescence microscopy. However, it was found that this probe did not accumulate into secretory vesicles of model cells. Therefore, FFN42 is currently the best bioelectrofluorescent compromise. Additionally, the effects of a transparent and conducting indium tin oxide (ITO) microdevice on electrochemical performances and reusability were examined.
