Effects of Cryo-grinding on the Extraction and Physicochemical Properties of Silk Fibroin
Herein, cryo-grinding technique was introduced into the extraction process of silk fibroin, aiming to achieve efficient preparation and controllable performance of silk fibroin.More specifically, the cocoon was pre-frozen in liquid nitrogen for 12 h before being ground, and the physical and chemical properties of the obtained sample (GSF322) were c
