Amphiphilic Block Copolymer Nanotubes and Vesicles Stabilized byPhotopolymerization



Ana Jofre, John B. Hutchison, Laurie E. Locascio, Kristian Helmerson


Photopolymerization is implemented to crosslink and stabilize vesicles and nanotubes composed of amphiphilic block copolymer chains. Stabilized membranes of nanotubes and vesicles were formed by the directed self-assembly of poly(ethylene oxide)-block-polybutadiene followed by UV-initiated photopolymerization to a maximum double bond conversion of 15%. The applicability of photopolymerization for biophysics and bioanalytical science is demonstrated by electrophoresing DNA molecules through a stabilized nanotube with an integrated vesicle reservoir.
