With the increasing of the food safety awareness, the quality control of amaranth as the common food additives was significant for human’s physical health. The objective of this study was to establish a green, simple, and rapid fluorescence sensor for amaranth quantification detection. The nitrogen-doped graphene quantum dots (NGQDs) were synthesized under a friendly environment and non-toxic material...
Hydrogen sulfide (H2S) has been involved in many foodstuffs and beverages. On-site measuring the H2S level in food samples was beneficial to the concerns about food safety and food quality. Herein, we rationally constructed a novel fluorescent probe to track the H2S levels in various food samples. The optical experiments indicated that the probe displayed highly selective and sensitive response to...
