利用原子力显微镜研究了蓖麻蚕丝素蛋白纳米结构的形成过程。我们已经观察到高度有序的纳米级纺织品状结构的丝素分子。AFM和SDS-PAGE实验表明，丝素分子具有刚性的棒状结构，并通过端对端的相互作用形成聚集体。与家蚕丝素蛋白相似，S. C.蓖麻丝心蛋白被认为是通过分子的静电相互作用组装的。
Atomic force microscopy was adopted to study the nanoscopic structure formation of natural fibrous protein, fibroin from the Samia cynthia ricini wild silkworm. We have observed highly ordered nanoscale textile-fabric-like structures of fibroin molecules. From AFM and SDS-PAGE experiments, it was revealed that fibroin molecules have a rigid rodlike structure and form aggregates by end-to-end interactions of molecules. By analogy with Bombyx mori fibroin, S. c. ricini fibroin is supposed to assemble by electrostatic interactions of molecules.
