Abstract

The present work emphases on the development of a sensor constructed based on the carbon quantum dots (CQDs) doped with heteroatoms such as nitrogen and phosphorous (NPCQDs) by one step microwave radiation assisted method. Cyclic voltammetry and chronoamperometry are used to investigate and compare the sensing performance of CQDs, nitrogen doped CQDs (NCQDs), phosphorous doped CQDs (CQDs) and NPCQDs towards glucose and lactate. It is observed that NPCQDs shows enhanced current response compared to CQDs, NCQDs and PCQDs due to the injection of extra electrons by dopants. Further, NPCQDs sensor exhibited good stability over 5000 s which is excellent in its class.

作为葡萄糖和乳酸传感器的氮磷共掺杂碳量子点

本研究通过一步微波辐射辅助法，重点开发了一种基于掺杂氮和磷等杂原子的碳量子点（CQDs）的传感器。利用循环伏安法和计时电流法研究和比较了 CQDs、掺氮 CQDs（NCQDs）、掺磷 CQDs（CQDs）和 NPCQDs 对葡萄糖和乳酸盐的传感性能。与 CQDs、NCQDs 和 PCQDs 相比，由于掺杂剂注入了额外的电子，NPCQDs 显示出更强的电流响应。此外，NPCQDs 传感器在 5000 秒内表现出良好的稳定性，在同类产品中非常出色。
