Selective and sensitive detection of melamine by intra/inter liposomal interaction of polydiacetylene liposomes

Chem Commun (Camb). 2011 Jan 7;47(1):358-60. doi: 10.1039/c0cc02183k. Epub 2010 Sep 14.

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.
