Protein Fiber

Silk fibroin (SF) is a protein fiber spun by Bombyx mori silkworm. SF fibers are about 10-25 μm wide in diameter and a single cocoon may provide over 1000 m of SF fibers. SF can present several conformations regarding protein secondary structure which ultimately define the structural properties of SF-based materials. For this reason, a rigorous control on its processing conditions shall be performed. It is known that SF has excellent properties to be used in biomaterials field, controlled release and scaffolds for tissue engineering. In addition, SF can be processed in several forms, such as films, fibers, hydrogels or microparticles. This work seeks to provide an overview on SF processing conditions, regarding the preparation of SF membranes (dense and porous), hydrogels and biocomposites, focusing on biomaterials application.

This study explores a series of optical, physical and structural properties based on P2O5-Al2O3-ZnO (ZAP) with glass doped 1 mol% Tb2O3, which changed the composition ratio between ZnO and P2O5. The structure and optical of glasses were studies by Raman spectra and fluorescence spectra. The Raman spectra with the zinc content increases, the 650-810 cm-1 at the P-­O­-P bond has no shift, but the intensity of the absorption peak decreased. The fluorescence intensity increases with the ZnO content increases. The glass density and refractive index also increases with the ZnO content increases.
