In 1600 BC Greek surgeon Galen of Pergamon used silk to suture together gladiators’ severed tendons. This is the first noted use of silk in the medical field. Since then, silk has paved its way into the healthcare industry. It has garnered special attention which can largely be attributed to its excellent material properties, affordability, and resource ability. Today, it's more than just a suture material. Silk is a protein polymer that is secreted by a variety of species such as spiders, moths, and butterflies. It has notable properties like low immunogenic response, biodegradability, and biocompatibility. Additionally, studies have proven that silk supports human keratinocytes and fibroblast growth. These factors make it ideal for use in engineering artificial tissue and give it an added advantage over other biomaterials. In 1992 - technology was discovered - to convert silk fiber into liquid silk. This opened up large possibilities. The liquid silk can then be cast into mater...
