Hierarchical magnetic nano-orb-assisted fluorescence recovery aptasensor for sensitive detection of aflatoxin M1 in milk.

Aflatoxin M1 (AFM1) contamination in milk and dairy products poses a significant food safety concern, highlighting the need for sensitive and reliable analytical methods. Herein, we developed a fluorescence recovery aptasensor that integrates hierarchical magnetic nano-orbs (HMO) as magnetic capture probes with aptamer...

Entropy-Engineered Aptamer Truncation Enables Dual-Mode LRET/SERS Aptasensing for Multiplex Detection of Phalloidin and α-Amanitin in Mushroom Samples.

Phalloidin (PHD) and α-amanitin (α-AMT) are structurally constrained cyclic mushroom toxins whose rigid structures and limited accessible recognition surfaces challenge high-affinity molecular recognition and sensitive multiplex detection. Here, we report an entropy-guided aptamer engineering strategy that removes redu...
