Applications in interfacial processes. (IMAGE)
Caption
a, Versatile interfacial process platform based on CPFs. The reactant is first dispersed into a liquid array using capturers. After the interfacial processes, by contacting the capturers with liquid films, the dispersed liquid can be completely recovered to facilitate product processing. b, Reversible sampling and release demonstration. The insulin release curve of the CPFs, cotton swab and flocking swab in water (data are presented as mean ± s.d. of n = 3 replicates). c, Influenza virus sampling and detection results of the CPFs, cotton swab and flocking swab. d, Schematic illustration of bacterial encapsulation. After encapsulation by interfacial gelation, the Acetobacterium are confined in the semi-permeable membrane, the reactants can enter the membrane timely to be replenished and the products can diffuse out. e, Concentrations of acetate and suspended bacteria in solution versus time. f, Evaporative humidifier demonstration. The dry air passes through the water-captured CPF array, and the humidified air is output as the water droplets evaporate. The output humidity can be adjusted by the airflow rate (data are presented as mean ± s.d. of n = 3 replicates). g, Demonstration of CO2 capture. The CPF array first disperses the absorbent, and after absorbing CO2, the droplets are recovered by the soap film array for CO2 storage. Subsequently, heating the recovered liquid can release CO2 on demand. Scale bars, 3 mm.
