N,S co-doped carbon dots based fluorescent “on-off-on” sensor for determination of ascorbic acid in common fruits
Xueli Luo,Wengang Zhang,Yong Han,Xiumei Chen,Li Zhu,Wenzhi Tang,Jianlong Wang,Tianli Yue,Zhonghong Li +8 more
TL;DR: A switchable sensor based on N and S co-doped carbon dots was developed to determine ascorbic acid (AA) content in common fruits via fluorescence quenching of N,S-CDs by Fe3+ (off) and recovery by AA (on).

Surface molecularly imprinted polymer capped Mn-doped ZnS quantum dots as a phosphorescent nanosensor for detecting patulin in apple juice.
TL;DR: A Mn-doped ZnS quantum dots (QDs) based nanosensor for selective phosphorescent determination of patulin was synthesized with 6-hydroxynicotinic acid as dummy template via a surface molecular imprinting sol-gel process, demonstrating a specific recognition for PAT among competitive mycotoxins and its analogues.
