dc.description | We thank C. Li from the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, for help during synchrotron measurements at the μSpot beamline at BESSY at the Helmholtz-Zentrum Berlin für Materialien und Energie in Berlin, Germany. We acknowledge the provision of facilities and technical support by Aalto University at the OtaNano Nanomicroscopy Center (Aalto-NMC). This work was supported by the Academy of Finland project 348628, the Jenny and Antti Wihuri Foundation (Centre for Young Synbio Scientists), and the Academy of Finland Center of Excellence Program (2022–2029) in Life-Inspired Hybrid Materials (LIBER) project number 346106, and by internal funding from the VTT Technical Research Center of Finland Ltd. We also acknowledge the Dutch Research Council (NWO, domain Applied and Engineering Sciences: MYCOAT project number 18425) and the Horizon 2020 programs of the European Union (FUNGAR; project 58132 and iNEXT-Discovery, project 871037) for NMR studies. Furthermore, the high-field NMR experiments were supported by uNMR-NL, the National Roadmap Large-Scale NMR Facility of the Netherlands (NWO grant 184.032.207), and the uNMR-NL grid (NWO grant 184.035.002). | |
dc.description.abstract | High strength, hardness, and fracture toughness are mechanical properties that are not commonly associated with the fleshy body of a fungus. Here, we show with detailed structural, chemical, and mechanical characterization that Fomes fomentarius is an exception, and its architectural design is a source of inspiration for an emerging class of ultralightweight high-performance materials. Our findings reveal that F. fomentarius is a functionally graded material with three distinct layers that undergo multiscale hierarchical self-assembly. Mycelium is the primary component in all layers. However, in each layer, mycelium exhibits a very distinct microstructure with unique preferential orientation, aspect ratio, density, and branch length. We also show that an extracellular matrix acts as a reinforcing adhesive that differs in each layer in terms of quantity, polymeric content, and interconnectivity. These findings demonstrate how the synergistic interplay of the aforementioned features results in distinct mechanical properties for each layer. | en |
