(Pubs.ACS.org) A bionic mushroom was created by intertwining cyanobacterial cells with 3D printed graphene nanoribbons (GNRs) onto the umbrella-shaped pileus of mushroom for photosynthetic bioelectricity generation. A 3D printing technique was used to assemble the cyanobacterial cells in a densely packed geometry resulting in adequate cell-population density for efficient collective behavior. This study was conducted by the Department of Mechanical Engineering, Stevens Institute of Technology, New Jersey.
The 3D printed cyanobacterial colonies resulted in comparatively higher photocurrent (almost 8-fold increase) than cyanobacteria of similar seeding density. The present study augments scientific understanding of multidimensional integration between the living biological microworld and functional 3D printed abiotic nanomaterials to establish advancement of bacterial nanobionics.
NOTE: Cynobacteria are photosynthetic bacteria that are single-celled but often form colonies in the form of filaments, sheets, or spheres.
