The mechanism of β-sheet crystallization in silk fibroin remains unclear, due to the
incomplete information of protein assembly and structural state. The emerging terahertz
(THz) spectroscopy (< 10THz) has been taken as an important tool to detect new aspects of biomolecular structure and is used for the first time to analyze the methanol–water (MeOH) induced structural changes of Bombyx mori silk fibroin. Mid-infrared spectroscopy (IR) and ...
