Probing membrane asymmetry of ABC polymersomes

Abstract

We report the sensitivity of the membrane asymmetry of ABC (PEO-b-PCL-b-PMOXA) polymersomes towards the end-group modification of a shorter C block. While a non-modified ABC polymer formed polymersomes with the A block outside and the C block inside, a mixture of ABC and ABC-biotin formed polymersomes with the C block outside.
