Development of an aptamer-based SPR-biosensor for the determination of kanamycin residues in foods

Écija-Arenas, Ángela ; Kirchner, Eva-Maria ; Hirsch, Thomas ; Fernández-Romero, Juan Manuel


A biosensor in which an affinity reaction occurs in the sensitive microzone through the use of specific aptamers to determine kanamycin residues in agri-food samples has been developed. It is an irreversible and continuous flow aptameric biosensor (aptasensor) in which the signal variations are monitored by surface plasmon resonance (SPR) measurements based on the specific interaction of the ...
