Figure 2. Polymersome membranes have been designed to interact with other polymersomes or cells and to respond to stimuli.
(A, B) Modification of polymersome surfaces with antibodies and ligands can allow polymersomes to mimic some adhesive and targeting abilities of immunological cells. . (C) Composite polymersomes loaded with a porphyrin based fluorophore and dextran rupture in response to light. (D) Block copolypeptides can be induced to assemble into a membrane in response to a pH shift. (B) Adapted from reference 42. Reproduced by permission of The Royal Society of Chemistry.
