title: Label-free aptamer-based sensors for L-argininamide by using nucleic acid minor groove binding dyes.
abstract: The nucleic acid minor groove binding dyes, DAPI and Hoechst 33258, were for the first time used in label-free aptamer-based sensors for L-argininamide. The synergy binding effect results in the enhancement of fluorescence of dyes. The method for detection of L-argininamide is simple, rapid and cost-effective.
