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...
