Abstract

Abstract: The light‐triggered, programmable rupture of cell‐sized vesicles is described, with particular emphasis on self‐assembled polymersome capsules. The mechanism involves a hypotonic osmotic imbalance created by the accumulation of photogenerated species inside the lumen, which cannot be compensated owing to the low water permeability of the membrane. This simple and versatile mechanism can be adapted to a wealth of hydrosoluble molecules, which are either able to generate reactive oxygen species or undergo photocleavage. Ultimately, in a multi‐compartmentalized and cell‐like system, the possibility to selectively burst polymersomes with high specificity and temporal precision and to consequently deliver small encapsulated vesicles (both polymersomes and liposomes) is demonstrated. Abstract : Pop goes the polymersome : A versatile protocol is described for the controlled light‐triggered rupture of giant polymersomes. This method allows the precise and selective delivery of a range of loaded species with full control in time, space, and excitation wavelength.
