Biomaterials fabricated from all‐aqueous microfluidics as biomimetic microreactors. a) Schematics of enzymatic production of CaCO₃ mineral within liposome‐coated ATPS vesicles. b) (Upper line) Schematics of the experiment, in which the effect of adding Ca²⁺ to a sample of liposome‐coated ATPS vesicles is evaluated. At 5 × 10⁻³ m Ca²⁺ and above, the interfacial layer of liposomes is disrupted. (Bottom line) CLSM images of liposome‐coated ATPS vesicles with different amounts of added Ca²⁺ as indicated in each panel. Scale bar: 10 µm. c) The sequential enzyme reaction of GOX and HRP with the corresponding substrates and products. d) Schematic of the GOX and HRP catalyzation in an ATPS‐based heterogeneous media. a,b) Reproduced with permission.211 Copyright 2015, American Chemical Society. c,d) Reproduced with permission.220 Copyright 2014, American Chemical Society.
