This study was focused on the conformational characterization of Bombyx mori silk Γbroin in Γlm, Γber and powder form by means of Fourier transform Raman spectroscopy. Native and regenerated silk Γbroin Γlms prepared by casting dilute silk Γbroin solutions (AE1% , w/v) display characteristic conform
Bombyx mori silk fibroin from the silkworm was found to be soluble in a calcium nitrate-methanol system. Fibroin dissolves in 75% w/v Ca(NO 3 ) 2 /MeOH solution at a temperature of 67ΠC. The viscometric behavior of the fibroin-salt solution was analyzed and the fibroin's secondary structures were de
We performed atomic force microscopy measurements on fibroin molecules from the domestic silkworm, Bombyx mori. At low concentrations, we could observe single protein molecules. The shape of the observed molecules is a rod with long smaller chains extending from the ends. The size of the rod is 60 n
