Thermo‐Responsive Microcapsules: Thermo‐Responsive Microcapsules with Tunable Molecular Permeability for Controlled Encapsulation and Release (Adv. Funct. Mater. 24/2021)

In article number 2100782, Shin-Hyun Kim and co-workers design thermo-responsive microcapsules with ultra-thin hydrogel membranes. The microcapsules show molecular-size-selective transmembrane permeation due to the consistent mesh size of the hydrogel membrane. More importantly, the cut-off threshold of permeation can be reversibly adjusted by temperature control. Therefore, the microcapsules provide molecule-selective encapsulation and controlled release of the encapsulants in a programmed manner.
