The design and exploration of efficient, stable and environmentally compatible organic emitters for an electrochemiluminescence (ECL) sensor is a promising topic. Herein, a novel environmentally-friendly luminophore, ZnBCBTP@MWCNTs, were fabricated via self-assembly of porphyrin molecules (ZnBCBTP) onto multi-walled carbon nanotubes (MWCNTs). The resulting luminophore ZnBCBTP@MWCNTs displayed not only the highly ECL property and but also the good accelerated electron mobility. Then, a label-free ECL biosensor based ZnBCBTP@MWCNTs was constructed for the ultrasensitive detection of uric acid. Excitingly, this proposed ECL biosensor performed a good linear relationship in the range of 0–300 μM with a low detection limit of 1.4 μM, thus offering another reliable and feasible sensing platform for clinical bioanalysis with good selectivity, stability, and repeatability.

卟啉与多壁碳纳米管协同作用增强电化学发光检测尿酸

设计和探索用于电化学发光（ECL）传感器的高效、稳定和环境兼容的有机发射器是一个很有前景的课题。在此，通过卟啉分子（ZnBCBTP）在多壁碳纳米管（MWCNTs）上的自组装制备了一种新型环保发光体ZnBCBTP@MWCNTs。所得发光体 ZnBCBTP@MWCNTs 不仅表现出高 ECL 性能，而且还表现出良好的加速电子迁移率。然后，构建了一种基于 ZnBCBTP@MWCNTs 的无标记 ECL 生物传感器，用于超灵敏检测尿酸。令人兴奋的是，该ECL生物传感器在0-300 μM范围内表现出良好的线性关系，检测限低至1.4 μM，从而为临床生物分析提供了另一个可靠可行的传感平台，具有良好的选择性、稳定性、
