Engineering motile aqueous phase-separated droplets via liposome stabilisation

Nature Communications, 2021
Bio-mimetic motion has been hard to achieve due to a lack of biocompatible conditions. Here, the authors report the creation of a liposome-stabilised aqueous PEG/dextran Pickering-like emulsion system with motion induced by the Marangoni effect and ...
