Figure 13.

The schematic illustration of plant part-derived CDs for the sensing of drugs in biological samples. The enhancement of FL emission intensity in CD/Fe³⁺ and CD/Hg²⁺ was shown after interactions with ZA and chemet, respectively. The interaction of CDs with SASP, MTX, PC, and TC produced an FL quenching effect. The real sample analysis of all analytes was performed in different biological samples. Abbreviations: ZA, zoledronic acid; SASP, salazosulfapyridine; MTX, methotrexate; PC, prilocaine; TC, tetracycline.
