菌丝体水凝胶三维打印成活体复合材料
Three-dimensional Printing of Mycelium Hydrogels into Living Complex Materials
摘要：
生物活材料，如动物骨骼和植物茎，能够自我修复，再生，适应和在环境压力下做出决定。尽管最近成功地将这些卓越的功能注入合成材料，但在生物学中发现的复杂适应系统的许多新兴特性在工程生物材料中仍未被探索。在这里，我们报告了一种三维打印方法，该方法利用真菌菌丝体的新兴特性来创造活的复杂材料，这些材料可以自我修复，再生和适应环境，同时实现工程功能。装载真菌灵芝的水凝胶被3D打印成网格结构，以使菌丝体以平衡的探索和开发模式生长，同时促进凝胶的定植和空气间隙的桥接。为了说明这种复杂材料的潜力，我们3D打印了一种机械坚固，自清洁，并且能够在损坏后自主再生的机器人皮肤。
英文摘要：
Biological living materials, such as animal bones and plant stems, are able to self-heal, regenerate, adapt and make decisions under environmental pressures. Despite recent successful efforts to imbue synthetic materials with some of these remarkable functionalities, many emerging properties of complex adaptive systems found in biology remain unexplored in engineered living materials. Here, we report on a three-dimensional printing approach that harnesses the emerging properties of fungal mycelium to create living complex materials that self-repair, regenerate and adapt to the environment while fulfilling an engineering function. Hydrogels loaded with the fungus Ganoderma lucidum are 3D printed into lattice architectures to enable mycelial growth in a balanced exploration and exploitation pattern that simultaneously promotes colonization of the gel and bridging of air gaps. To illustrate the potential of such living complex materials, we 3D print a robotic skin that is mechanically robust, self-cleaning, and able to autonomously regenerate after damage.
