Abstract
The influence of ultrasonic treatment on the fibroin conformation in solutions and films was studied by dynamic light scattering, FTIR spectroscopy, and X-ray diffraction. Ultrasonic treatment of fibroin solutions leads to a decrease in the fraction of the α-helical conformation and to an increase in the fraction of β-turns and β-structure in the fibroin structure in the films regenerated from solutions.
