摘要

掺硼金刚石（BDD）具有超宽电化学电位窗口和低背景电流的特点，适合作为实时检测的电化学分析电极。然而，平面BDD电极的实际应用受到其电导率低、活性位点少、检测灵敏度不足的限制，需要通过表面改性来改善。在本研究中，采用简单的CVD方法在BDD衬底上沉积了亚微米碳球（SMCS）。复合结构（SMCS/BDD）具有较大的比表面积和高电导率，提高了药物检测的灵敏度。这些结果表明，基于bdd的全碳材料具有用作医疗传感器电极的潜力。

Submicron spherical carbon modified boron-doped diamond for sensitive detection of sertraline hydrochloride

Boron-doped diamond (BDD) is suitable for use as an electrochemical analytical electrode for real-time detection because of its ultra-wide electrochemical potential window and low background current. However, the practical application of planar BDD electrodes is limited by their low conductivity, few active sites, and insufficient detection sensitivity, which need to be improved by surface modification. In this study, submicron carbon spheres (SMCS) were deposited on BDD substrate by a simple CVD method. The composite structure (SMCS/BDD) has a large specific surface area and high conductivity, which improves the sensitivity for drug detection. These results indicate that BDD-based all‑carbon materials have the potential to be used as electrodes for medical sensors.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
