Research topics from publications: Dual-response ratiometric fluorescent probe for visual and colorimetric detection of tetracycline; S,O-doped carbon nitride as a fluorescence probe for the label-free detection of folic acid and targeted cancer cell imaging; Multifunctional nanocomposites based on graphite-phase carbon nitride quantum dot-silver nanospheres for combined photothermal–photodynamic anti-tumor therapy. Representative work: A novel nanoprobe based on S,O-doped carbon nitride quantum dots (S,O-CNQDs) was designed and synthesized. The as-prepared S,O-CNQDs exhibits good biocompatibility and strong fluorescence at excitation 360 nm. It is found that folic acid (FA) could efficiently quench the fluorescence of S,O-CNQDs. The obtained S,O-CNQDs is capable of acting as a sensitive and selective probe for FA detection in the range 5.0–83.3 μM with a detection limit of 90 nM. The as-prepared probe has been successfully utilized for the detection of FA in various real samples with satisfactory recoveries (98.8–107 %) and small relative standard deviation (<5%). The reaction mechanism between S,O-CNQDs and FA has been di In this study, a g-CNQDs@AgNSs nanocomposite was successfully prepared based on graphite-phase carbon nitride quantum dots and silver nanospheres. Both in vitro and cellular experiments proved that the nanocomposite had good PTT/PDT effects, promising efficient combination therapy of tumors
