Recent Progress in Folic Acid Detection Based on Fluorescent Carbon Dots as Sensors: A Review

Carbon dot as fluorescence sensor for glutathione in human serum samples: a review

“…Until this point, significant endeavors have been invested in creating diverse CDs to function as efficient fluorescence probes for detecting GSH. Due to their widespread sources, minimal toxicity, excellent photoluminescence, and biocompatibility, 50 CDs have garnered significant attention and found widespread use in chemical sensing applications. In this context, fluorescent CDs sensors are categorized into three types based on different sensing approaches: single probe of CDs, ratiometric probe of CDs, and visual detection of CDs.…”

“…These molecules can be combined with others to introduce heteroatom doping atoms. [50][51][52][53] Due to its ability to interact with fluorescent species, compounds, or nanomaterials, GSH can be quantitatively assessed by monitoring (3) Signals arising from fluorescent nanomaterials, where GSH causes changes in fluorescence performance by perturbing surface properties or nanostructures. Among various fluorescent sensors, carbon dots have garnered significant attention as one of the most promising sensors for GSH due to their well-known nanomaterial properties with tunable fluorescence.…”
