Nitrogen, chloride doped carbon dots (N, Cl-CDs) were synthesized in deep eutectic solvent. TEM, XRD, FT-IR, XPS, EDAX, UV-Vis and fluorescence were used for characterization. Quantum yield and average size of N, Cl-CDs were 38.75 % and 2-3 nm, respectively. N, Cl-CDs fluorescence was turn off by cobalt ion and then turn on gradually after addition of enrofloxacin. Linear dynamic range and detection limit (DL) for Co and enrofloxacin were (0.1-70 µM and 30 nM) and (0.05-50 µM and 25 nM), respectively. Enrofloxacin was detected in blood serum and water samples with the recovery of 96-103 %. Finally, Antibacterial activity of the carbon dots was also investigated.
氮、氯掺杂碳点(N、Cl-CDs)在深共熔溶剂中合成。采用 TEM、XRD、FT-IR、XPS、EDAX、UV-Vis 和荧光对其进行了表征。N、Cl-CDs 的量子产率和平均粒径分别为 38.75%和 2-3nm。钴离子使 N、Cl-CDs 的荧光猝灭,然后加入恩诺沙星后逐渐恢复。Co 和恩诺沙星的线性动态范围和检测限(DL)分别为(0.1-70µM 和 30nM)和(0.05-50µM 和 25nM)。该方法用于检测血清和水样中的恩诺沙星,回收率为 96-103%。最后,还研究了碳点的抗菌活性。
