Facile Fabrication of Transparent and Opaque Albumin Methacryloyl Gels with Highly Improved Mechanical Properties and Controlled Pore Structures.

As shown in Figure S2 , cryogels obtained at −20 °C appeared not homogenous, and the pore morphology did not show a clear trend among samples with different concentrations possibly because the cryogelation at −20 °C might be not sufficient to support fast phase separation and radical polymerization simultaneously.
