Biosensor signal amplification of vesicles functionalized with glycolipid for colorimetric detection of Escherichia coli.

Yan-Lei Su1, Jin-Ru Li, Long Jiang, Jie Cao.   

Abstract

A supramolecular assembly of phospholipid-polymerized diacetylene vesicles functionalized with glycolipid can provide a molecular recognition function. The Escherichia coli-glycolipid binding event leads to a visible color change from blue to red, readily seen with the naked eye and quantified by absorption spectroscopy. The biosensor signal is amplified through a suitable increase of phospholipid content in the mixed lipid vesicles and pH of aqueous solutions.
