Article Abstract
An electrochemical biosensor was developed using boron-doped diamond (BDD) as an electrode material. To enhance the electrical performance of the electrode, the BDD electrode was decorated with Pt-nanoparticles (Pt-NPs) by electrochemical deposition. Their morphology according to the applied potentials for the synthesis of Pt-NPs was characterized by SEM. To identify the performance of the electrode modified with Pt-NPs, glucose detection was used as a sample sensing process, and the results were compared with those of a gold electrode and a bare BDD electrode. The electrochemical characteristics of the modified electrode were examined by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The BDD electrode with the Pt-NPs showed higher sensitivity and a lower detection limit than the Au electrode and BDD electrode. The proposed biosensor based on the Pt-NPs decorated BDD electrode showed high sensitivity, a low detection limit, fast direct electron transfer and good stability.

Various electrochemical tests were carried out to elucidate the electrolytic oxidation mechanism of oxalic acid on a boron-doped diamond electrode in a nitric acid environment. These included cyclic voltammetry, AC impedance, constant current electrolysis, and electron paramagnetic resonance spectroscopy. The impact of electrode potential, current density, nitric acid concentration, and electrode plate spacing on the oxidation of oxalic acid was investigated.

The highly efficient degradation of persistent organic substances by electrochemical advanced oxidation processes (EAOPs), which don't result in the formation of potentially harmful by-products, is crucial for the future of water management. In this study, boron-doped diamond electrodes (BDDE) with three morphologies (planar 2D, microstructured 2D, and macroporous 3D) were employed for the anodic oxidation of diclofenac (DCF) in two working electrolytes (NaCl and NaSO). In total, 11 by-products formed during the electrochemical oxidation of DCF were identified via HPLC-HRMS.

In this work, we pioneered the preparation of diamond-containing flexible electrodes using 3D printing technology. The herein developed procedure involves a unique integration of boron-doped diamond (BDD) microparticles and multi-walled carbon nanotubes (CNTs) within a flexible polymer, thermoplastic polyurethane (TPU). Initially, the process for the preparation of homogeneous filaments with optimal printability was addressed, leading to the development of two TPU/CNT/BDD composite electrodes with different CNT:BDD weight ratios (1:1 and 1:2), which were benchmarked against a TPU/CNT electrode.

The miniaturization of electrochemical supercapacitors (EC-SCs) requires electrode materials that are both durable and efficient. Boron-doped diamond (BDD) films are an ideal choice for EC-SC due to their durability and exceptional electrochemical performance. In this study, nanostructured boron-doped ultra-nanocrystalline diamonds (NBUNCD) are fabricated on Si micro-pyramids (Si) using a simple reactive ion etching (RIE) process.

Overuse of levofloxacin (LEV) is often associated with bacterial resistance and serious health problems, underscoring the need for reliable sensing and monitoring of LEV molecules. Therefore, this study aimed to investigate LEV using boron-doped diamond (BDD) and boron-doped diamond modified with MXene (TiCT) (BDD-MXene) electrode. The successful deposition of MXene on the BDD surface was confirmed using scanning electron microscope (SEM).
