Controlling the Molecular Structure and Physical Properties of Artificial Honeybee Silk by Heating or by Immersion in Solvents
Figure 3
Raman spectra of honeybee silk sponges treated by heating at different temperatures for periods of 10–120 min.
Inset shows the approximate ratio of Raman intensity at 1653 cm−1 (attributed to coiled coil protein structure) to intensity at 1669 cm−1 (attributed to ß-sheet protein structure) for different samples.
