The Synthetic Spider Silk Protein and The Artificial Spider Silk

Spider silk is Natural high-performance protein fiber. The biomaterial has attracted much interest from scientists in various disciplines. Now it has become feasible to produce spider silk proteins by means of biotechnology and the man-made spider silk fibers have been also produced by wet-spinning method. Artificial spider silk with mechanical properties similar to the nature spider silk should be able to be produced by varying the spinning parameters and post-process. Recent research about the recombinant spider silk proteins based on the genetic engineering and the artificial spinning of spider silk were reviewed in this paper.
