Abstract

Acetobacter xylinum secretes cellulose nano-fibers with 40-60nm in width. Recently, Kondo et al. reported the method to regulate the direction of the fiber secretion due to the strong interaction with the nematic ordered cellulose (NOC)1) template2). By the deposition of the secreted nano-fiber epitaxially with the same direction as the molecular orientation of the NOC, a 3D structure having a uniaxial lattice pattern was supposed to be automatically built by the incubation of the bacteria on the substrate. In this paper, a template having a desired pattern was made on the surface of a modified BC pellicle with a flat hydrophobic surface. The hydrophilic pattern was constructed by scratching the hydrophobic surface using AFM. When the bacteria were cultivated on this template, a 3D nano-architecture built on the hydrophilic pattern was proved to appear.
