Detection of sulphur(II) of carbon dots synthesized from residue.

The detection of anions using carbon dots (CDs) has received less attention compared to cations. Therefore, the present study aimed to develop a fluorescence sensor based on carbon dots (CDs) capable of detecting S in real water samples. The CDs were successfully prepared from the residues of a traditional Chinese herb, , which emitted green photoluminescence (PL) under ultraviolet light irradiation.

Design, synthesis and inhibitory activity against Candida albicans of a series of derivatives with 5-nitrofuran scaffold.

The increasing resistance of Candida albicans against the currently available antifungal drugs has exerted enormous damage to human health. To develop novel and efficient antifungal agents with unique structure, a series of derivatives containing 5-nitrofuran scaffold (33 examples) were designed, synthesized, and screened the in vitro antifungal activities. Bioassay results disclosed that 5-nitrofuran derivatives could dramatically inhibit the growth of six strains of Candida albicans, particularly the drug-resistant clinical ones.
