[Engineered spider silk: the intelligent biomaterial of the future. Part II].

The development and progress in engineered spider silk manufacturing has enabled its practical application. Recombinant spider silk can assemble in several morphological forms such as films, hydrogels, fibers, scaffolds, microcapsules, and micro- and nanospheres. The in vitro fiber formation takes place by mimicking the natural spinning process in the spider spinning gland: in the presence of phosphate ions and dragging forces.

[Engineered spider silk: the intelligent biomaterial of the future. Part I].

The unique properties of spider silk such as strength, extensibility, toughness, biocompatibility and biodegradability are the reasons for the recent development in silk biomaterial technology. For a long time scientific progress was impeded by limited access to spider silk. However, the development of the molecular biology strategy was a breaking point in synthetic spider silk protein design.
