Crystal modification of silk fibroin in liquid silk nanofibers

抄録

In this study, gel-like liquid silk (LS) obtained from the middle division of the middle silk glands of fully grown larvae of the domesticated Bombyx mori silkworm was dissolved into 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) and electrospinning was performed, and then the crystal modification of silk fibroin (SF) in the nanofibers by the water vapor or ethanol treatment at room temperature was investigated. It was confirmed that only silk2 crystal modification of SF could occur in both treatments.
