Fragment-Specific Stable Carbon Isotope Analysis for Screening the Authenticity of Red Yeast Rice Products

Monacolin K (MK) in red yeast rice (RYR) is structurally identical to pharmaceutical lovastatin in its lactone form, making their origins difficult to distinguish. This study examined the δ13C value of hydrolysis-derived 2-methylbutyric acid (2-MBA) as a fragment-specific screeni...

Carbon Dot-Based Sensors for Food Chemical Hazard Detection: Real-Food Applications, Sample Preparation, and Portable Analysis

Carbon dots (CDs) are a heterogeneous family of fluorescent carbon nanomaterials that includes carbon quantum dots (CQDs) as a subclass. Owing to their favorable fluorescence, surface chemistry, and functionalization potential, CDs have been widely investigated for sensing analyt...
