Innovative biofibers made from a silk protein of the green lacewing are being developed at the Fraunhofer Institute for Applied Polymer Research IAP in conjunction with the company AMSilk GmbH. Researchers are working on producing the protein in large quantities by using biotechnology. The aim is to use the material in the future as a high-grade rigid fiber, for example, in lightweight plastics in transportation technology. It can also be conceivably used in medical technology, for example, as a biocompatible silk coating on implants. The Fraunhofer IAP is presenting its initial material sample at the International Green Week Berlin from January 20 to 29, 2017 in Hall 4.2, booth 212.
