In vivo real-time detection of pharmacokinetics of systemically administrated drugs in microenvironments advance pharmacology and clinical medicine. Here, we describe an analytical platform targeting dermal interstitial fluid with a needle-type microsensor of a boron-doped diamond (BDD) electrode. A test analyte was doxorubicin, an anticancer drug that induces acute cardiotoxicity. Upon intravenous bolus injection of doxorubicin to anesthetized rats, a BDD microsensor inserted into the dermis unexpectedly detected two sequential phases of the concentration change: a first component elicited in several minutes with fast kinetics and a sharp peak, and a subsequent second response maximized from 15 min to 1 h with slow kinetics. Furthermore, the BDD microsensing system was combined with electrocardiography, visualizing a relationship between doxorubicin's behavior in the skin and induction of QT-interval prolongation. Our approach may clarify detailed local pharmacokinetics and its correlation with pharmacodynamics and provide a prototype wearable device for next-generation drug monitoring.

ABSTRACT The production of municipal sludge is increasing rapidly, and the disposal of large amounts of sludge has become a significant challenge in urban development. This study investigates the mechanism and effect of the dewatering pretreatment of municipal sludge using boron-doped diamond (BDD) electrodes. Orthogonal experiments were designed to determine the optimal current density, temperature, pH, and reaction time, using sludge specific resistance (SSR) as the evaluation index. Under these optimal conditions, the BDD electrode disrupted extracellular polymers, cell walls, and cell membranes of sludge microorganisms, as quantified by Coomassie Brilliant Blue-G250 and anthrone colorimetric methods, alongside UV spectrophotometry. Low-field nuclear magnetic resonance (LF-NMR) T2 patterns revealed the transformation of interstitial water in the sludge to free water. Free radical masking experiments and Fourier transform infrared spectroscopy (FTIR) indicated that the presence of ·OH radicals significantly reduced hydrophilic functional groups (-OH, N-H, C-O, -COOH, and -C-O-C-) in extracellular polymeric substances (EPS), thereby reducing hydrophilicity and enhancing dewatering capacity. These findings demonstrate that BDD electrode treatment significantly enhances sludge dewaterability by generating ·OH radicals, which disrupt cellular structures and attack hydrophilic functional groups in EPS, consequently converting bound water into free water.

ABSTRACT One of the grand challenges in physics is the exploration of room‐temperature superconductivity and the promising candidate is hydrides under high‐pressure. In this review, we introduce a custom‐designed diamond anvil cell equipped with boron‐doped diamond electrodes that enables both the synthesis and in situ evaluation of superconductivity under extreme conditions without complex experimental configurations. The metallic boron‐doped diamond epitaxial film is selectively grown on the diamond anvil surface by microwave‐assisted plasma chemical vapor deposition, combined with lithographic patterning techniques. We describe the fabrication process of the boron‐doped diamond electrodes and demonstrate their application to the synthesis and transport measurements of superconducting hydrides. This approach provides a powerful and reusable platform for exploring new superconductors at ultrahigh pressures.

This work describes the development of a voltammetric method for the determination of telmisartan (TEL) employing an anodically pretreated boron-doped diamond electrode (AP-BDDE). In this electrode, TEL presented an irreversible peak at +1.33 V (vs. Ag/AgCl), which was associated with its oxidation involving two electrons and two protons. From the combination of electrochemistry and NMR spectroscopy data, it was possible to propose for the first time the reaction of oxidation for the TEL molecule onto the BDDE. Parameters recommended by validation guidelines were evaluated to validate the proposed method. Using differential pulse voltammetry, a linear plot was obtained for TEL in the concentration range 10-109 nmol L-1 in acetate buffer (pH 5.0), with a limit of detection of 0.16 nmol L-1. The selectivity of the methods was assessed against urine and water interferers, showing relative standard deviation values below 8%. The proposed method was successfully applied to pharmaceutical, environmental, and biological samples, exhibiting profiles consistent with green analytical chemistry, as confirmed by an assessment using the AGREE approach from the literature.
