title: Selective and sensitive detection of melamine by intra/inter liposomal interaction of polydiacetylene liposomes.
abstract: We report a convenient melamine detection system based on polydiacetylene (PDA) liposomes having rapid, selective, and sensitive detection, and dual signal capabilities. The detection limit of the sensory PDA liposome is 1 and 0.5 ppm in the colorimetric and the fluorescence detection schemes, respectively, satisfying the world regulation level.
