The post-processing temperature or humidity can importantly control the secondary structure and characteristics of silk fibroin films.

Temperature and humidity (TH) are highly important factors that can control the secondary structure and characterization of silk fibroin (SF) biomaterials. In this study, the water stability, secondary structure, mechanical properties, surface morphology, and degradation of silk fibroin films (SFFs) with post-processing in different TH were investigated. Fourier transform infrared indicated that the SFF secondary structure did not change under low-relative humidity (RH) despite temperatures up to 180°C, while it transformed at 40°C with 100% RH in 10 min.

Degraded Sericin Significantly Regulates Blood Glucose Levels and Improves Impaired Liver Function in T2D Rats by Reducing Oxidative Stress.

Sericin could be degraded well into low-molecular-weight sericin (SS) through a novel and environmentally friendly recycling process using an ultrasonically degumming method in Ca(OH) aqueous solution. The oral administration of the SS has an evidently hypoglycemic effect on STZ-induced T2D rats. At oral doses of 2.
