K2A8 strain as representative of the pool of strains. (a) Micro-pattern characterization. Hexagonal pattern of the surface-microstructured BC manufactured using biolithography. Hexagonal pattern-formation was observed by BF microscopy at high magnification ×20 using native BC. (b) SEM image of surface-microstructured BC. (c) SEM image of microstructured BC fibrous network. (d) SEM image of K2A8 present among microstructured BC fibrous network.
