All‐aqueous interfacial complexation via electrostatic interactions. a) Schematics of the electrospray setup. b) A typical capsule made by electrospray with PDADMAC and PSS and dialyzed against water to fully inflate; inset is the capsule as made before dialysis; scale bars: 100 µm. c,d) Formed PDADMAC/PSS microcapsules and encapsulated RD70 dye (red signal) imaged with CLSM; scale bars: 100 µm. e) Schematics of the fabrication process of the assembled PE microcapsules via affinity partitioning. f) Optical microscope and SEM images of the fabricated microcapsules with different PE combinations; scale bars: 300 µm. a–d) Reproduced with permission.189 Copyright 2016, American Chemical Society. e,f) Reproduced with permission.195 Copyright 2016, American Chemical Society.
