Label-free bacterial detection using polydiacetylene liposomes

Chem Commun (Camb). 2016 Aug 16;52(68):10346-9. doi: 10.1039/c6cc03116a.

Abstract

Polydiacetylene (PDA) liposomes were prepared to selectively capture target released from bacteria. Specific interplay between released-surfactin and PDA resulted in a conformal change in the structure of PDA, highlighting the potential of indirect interactions between bacteria and PDA in the construction of new label-free bacterial sensors.
