Abstract

Amphiphilic diacetylenes (DAs) can self-assemble into photopolymerizable liposomes that can be used to construct effective pathogen sensors. Here, modified commercial inkjet printers are used to disperse DAs into water, facilitating self-assembly. The liposomes are of similar size, but are significantly less polydisperse than liposomes formed using conventional sonication methods. The process is efficient, readily scalable and tolerant of structural modification. The derivitization of approximately 5% of the DA head groups and the incorporation of fluorophores into the hydrophobic bilayer allows for the preparation of novel multifluorophore PDA sensing systems that can provide enhanced bacterial discrimination in a single experiment by way of a fluorescent fingerprint.
