1. Introduction
Conjugated polymers have been broadly explored as colorimet-ric sensing materials due to their attractive optical and electricalproperties. These properties primarily result from an extensivedelocalized -system and intrinsic conformational restrictions with in the polymer chain [1].Among the conjugated polymers reported to date, PDAs are one of particular interest because they can change color from blue to redinresponse to external stimuli and can be auto-arranged in lipo-some assembly [2–8]; these characteristics could be manipulatedby lipid insertion modifying biointerfacial interactions and it couldbe utilized in sensing technologies to improve biosensors [9,10].The polydiacetyIn general, the insertion of lipids into PDA liposome has advan-tages in modifying PDA physical properties such as size [9], surfacecharge, and lipid packaging [11] which, in turn, affect sensitiv-ity and stability of PDA liposome biosensor [12–14]. It has been
