Science Alert December 1, 2021 Based on the living cells ability to synthesize molecular components and precisely assemble them to build living functional architectures under ambient conditions microbial engineering has produced materials for various applications. However, building 3D structures in arbitrary patterns and shapes has been a challenge. A team of researchers in the US (Harvard University, Northeastern University, Harvard Medical School) has developed a bioink (microbial ink) that is produced entirely from genetically engineered microbial cells, programmed to perform a bottom-up, hierarchical self-assembly of protein monomers into nanofibers, and nanofiber networks that comprise extrudable hydrogels. They demonstrated the 3D […]
