Microfluidic fabrication and permeation behaviors of uniform zwitterionic hydrogel microparticles and shells

- A microfluidic method was developed to generate uniform zwitterionic hydrogel microparticles and shells.
- Mesh size of the hydrogel network was characterized by the Peppas-Merrill equation and NMR cryoporometry.
- Manipulation of the mesh property enabled fabrication of hydrogel microparticles with controlled permeability.
