The Relationship between the Structures and Mechanical Properties of A. pernyi Silk
Animal silks have drawn the attention of biologists,chemists,and material scientists for more than a century. The recent resurgence in scientific interest in such materials,which have evolved independently in spiders as well as a wide range of insects,is due to the silks marvelous combination of modulus,strength and extensibility. After intensive study,the scientists have gained considerable knowledge about the primary sequences (although often only partial) of a wide range of natural silk proteins,and about the secondary structure of certain motifs. However,it is still less understood about the details of how the secondary structures arrange and organize into the condensed state structure at a higher level in the natural silks,and how these secondary structures contribute to the remarkable mechanical properties of the natural silks. It seems to still be a long way from producing artificial silk fibers comparable to those masterpieces produced by the spiders or silkworms themselves,whether the regenerated silk protein solutions or recombinant ones are used.
