Description
Summary: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. [Display omitted] •Non-enzymatic glucose sensors have gained interest in the research community.•Carbon quantum dots are good candidate for development of glucose sensor.•Developments and future perspectives of carbon quantum dots based glucose and lactate sensor fabrications are discussed.
