Aptamer-gated FRET nanosensor based on UCNPs-AuNSs for sensitive detection of methylmercury in seafood matrices.
Methylmercury (CH3Hg+) is the most toxic form of mercury found in fish, shellfish, and other aquatic organisms and poses significant risks to human health through the food chain. The present study reports the development of a fluorescence aptasensor for the quantification of CH3Hg+ using aptamer-functionalized gold nan...
