AMSilk is a German BioTech StartUp that developed the first industrial cleantech solution for manufacturing silk-based products. Scientists at the Technical University of Munich have successfully researched the code for spider silk proteins and are now able to create and produce tailor-made biopolymers. These biopolymers are the building blocks for many new products and applications ranging from textiles and nonwovens over modifiable films and surface coatings and particles for pharmaceutical products to cosmetics.[1][2] AMSilk was founded in 2008 and is located at the IZB (Innovation and start-up center for Biotechnology) in Planegg near Munich. Projects are partially funded through grants from the German Federal Ministry of Education and Research and the Bavarian Ministry of Economic Affairs, Infrastructure, Transport and Technology with project management provided by VDI (The Association of German Engineers). The company has won various awards, amongst them the national competition “365 Landmarks in the Land of Ideas” [3] and was part of the German pavilion at the Shanghai World Expo of 2010[4] as well as a finalist in the Entrepreneur of the year 2013 competition by Ernst&Young [5] AMSilks production process requires no fossil fuel-based reagents and is environmentally friendly. The silk proteins retain the basic silk properties found in natural spider silk proteins. In addition to being extremely tough, highly ductile and breathable, they are hypoallergic and biocompatible. In November 2013 AMSilk launched its first own cosmetic line under the brand name Spidersilk.[6]

Many different usage options for the silk protein have been developed. As of now, AMSilk is able to construct a range of interstage high-performance materials to be used to improve already existing products or to develop materials for completely new applications. [7]
