Biomaterials fabricated from all‐aqueous microfluidics for encapsulating and delivering active proteins and therapeutic drugs. a) Relative activity of lysozyme, ɑ‐amylase, and β‐galactosidase dissolved in the same droplet phase after exposure to an organic solvent and an aqueous osmolyte solution, subjected to freeze‐drying and osmo‐solidification for 7 days. b) Antibody release from alginate‐based hydrogel particles; scale bar: 50 µm. c) Schematic illustration of preparation and stimulation of ATPS‐liposomes for encapsulating and releasing DOX. d) DOX release profiles of (left) simple aqueous liposome and (right) ATPS‐liposome. e) Fluorescence microscope images of the uptake of NBD‐PE labeled DOX loaded ATPS‐liposomes by HeLa cells; scale bars: 20 µm. a) Reproduced with permission.76 Copyright 2016, Royal Society of Chemistry. b) Reproduced with permission.215 Copyright 2015, Wiley‐VCH. c–e) Reproduced with permission.113 Copyright 2018, Elsevier.
