Tuning the Porosity of Dextran Microgels with Supramacromolecular Nanogels as Soft Sacrificial Templates (Small 45/2023)

Small, vol. 19

Abstract

Bio-Based Microgels In article number 2303783, Andrij Pich and co-workers report a versatile method to tune the porosity of dextran-based microgels. The size of mesopores (≤50 nm) in diameter is regulated by the variation of the polymer concentration. For the generation of the macropores (300 to 690 nm), pH-degradable supramacromolecular nanogels are used as a sacrificial colloidal template. Different sizes of the sacrificial nanogels are synthesized via precipitation polymerization and subsequently embedded in the polymer matrix of the microgels via droplet-based microfluidics. The authors demonstrate that uniform voids in the macropore range can be realized by degrading the incorporated sacrificial nanogels.
