Silkderived

Silkderived is a term used to describe materials, compounds, and products derived from silk proteins, typically the biopolymers fibroin and sericin, through processing and modification. It encompasses a range of silk-based polymers and composites designed for applications in biomedicine, textiles, and industrial uses. Silkderived materials leverage the natural properties of silk, including biocompatibility, strength, and controllable degradation.

Production and processing methods involve isolating silk proteins from natural silk fibers obtained from silkworm cocoons, followed by separation of fibroin and sericin. The proteins are then processed via dissolution, regeneration, or enzymatic treatment, and may be crosslinked, grafted, or blended with other polymers. Advanced forms include silk-derived hydrogels, nanofibers, films, and composite materials that incorporate inorganic or organic additives.

Key properties of silkderived materials include tunable mechanical performance, high toughness, and adjustable degradation rates. Crystallinity and the β-sheet content of the silk proteins influence strength and stability, while surface chemistry can be modified to influence cell interactions and protein binding.

Applications are broad and include biomedical uses such as sutures, tissue engineering scaffolds, wound dressings, and controlled drug delivery systems. In textiles and coatings, silkderived materials offer breathable, lightweight, and durable options. Emerging areas explore silk-derived substrates for flexible electronics, sensors, and environmentally friendly packaging.

Research and regulation vary by application, with ongoing work to improve scalable production, refine functionalization techniques, and address safety and regulatory requirements, particularly for medical devices and therapeutic use. See also: silk fibroin, sericin, biopolymers, biomaterials.
