Its application to silk fibroin endows the natural material with additional advantages that make it extremely well suited as scaffolding biomaterial for the treatment of tendon and ligament pathologies that demand short-term high mechanical performance along with utmost biocompatibility and cell interaction.<\/p>\n<h4><strong>Description of the technological base<\/strong><\/h4>\n<p>A novel spinning technology (SFS) allows the spinning of protein fibers through an inexpensive and environmentally friendly procedure that enables adapting the material to its intended use.<\/p>\n<p>Fibroin obtained from silkworm silk is processed into fibers exhibiting the excellent properties of the natural silks (biocompatibility and high performance) and are endowed with emergent properties such as mechanical pre-stressing and biological activity. This new combination of properties makes them ideal for applications in Medicine that range from sutures to scaffolding bioactive biomaterials for cell therapies and Tissue Engineering. In particular, these fibers are especially suited to treatments on diseased or injured tendons and ligaments, where the mechanical performance at early stages is critical.&nbsp;<\/p>\n<p style=\"text-align: center\"><em><strong><span style=\"font-size: small\">&ldquo;Biocompatible and bioactive high-performance biomaterials can be used in a wide range of orthopaedic therapies, increasing healing chances and decreasing convalescence time&rdquo;<\/span><\/strong><\/em><\/p>\n<p style=\"text-align: center\"><em><strong><span style=\"font-size: small\"><img fetchpriority=\"high\" decoding=\"async\" src=\"http:\/\/www.upm.es\/observatorio\/vi\/gestor_general\/recuperar_archivo.jsp?id=742\" alt=\"\" width=\"400\" height=\"321\" \/><\/span><\/strong><\/em><\/p>\n<h4><strong>Market demands<\/strong><\/h4>\n<ul>\n<li>There is an increasing need for the production of high performance, cell-responsive biomaterials for mechanical demanding applications such as sutures, threads and membranes for replacing or reinforcing structural supportive tissues and scaffolds in Tissue Engineering.<\/li>\n<li>This need is especially evident in the therapy of tendons and ligaments.
