Since 5000 years ago, silk has captivated and continues to amaze humans exploring its new exciting applications. Thanks to many cross-disciplinary types of research, it is now clear that silk is no more a simple fibre but an outstanding biopolymer. Before defining the current state of the art surrounding the field of silk-based materials for drug delivery, and looking toward their future, this chapter provides a general overview of silk proteins. Starting from the motivation of the research and the history of silk-based material, the chapter moves on describing different types of silk, with particular emphasis on Bombyx mori and spider ones. Then, a detailed description of the primary and secondary structure of silk proteins (fibroin/spidroin and sericin) is provided. The most common degumming processes and the modern biomedical applications for both fibroin and sericin are also reported.

Abstract
Since 5000 years ago, silk has captivated and continues to amaze humans exploring its new exciting applications. Thanks to many cross-disciplinary types of research, it is now clear that silk is no more a simple fibre but an outstanding biopolymer. Before defining the current state of the art surrounding the field of silk-based materials for drug delivery, and looking toward their future, this chapter provides a general overview of silk proteins. Starting from the motivation of the research and the history of silk-based material, the chapter moves on describing different types of silk, with particular emphasis on Bombyx mori and spider ones. Then, a detailed description of the primary and secondary structure of silk proteins (fibroin/spidroin and sericin) is provided. The most common degumming processes and the modern biomedical applications for both fibroin and sericin are also reported.File | Dimensione | Formato | |
