Over the last years, the interest in materials consisting of biomolecules arranged in nanofibers increased. There is a special focus on plasma proteins for applications in nanofiber materials because of their high biocompatibility. An easy feasible strategy to create these nanofibers is the self-assembly mechanism of protein molecules. Here we test the hypothesis that novel self-assembled hybrid protein nanofibers (PNF) can consist of two different proteins. In this work, we present self-assembled plasma hybrid PNF consisting of two different plasma proteins. Further, long-time CD-measurements provide information about the fiber formation dynamics. Especially, for the PNNF hybrid it confirmed interactions between both molecules. We confirmed the existence of a novel PNF hybrid by tip enhanced Raman spectroscopy and immunolabeling. Also, differences in the mechanical behaviour were shown by force spectroscopy. These results lay the foundation for a novel biomaterial based on these (h)PNNFs.
