Transfer-printing of highly aligned DNA nanowires.

We developed a simple method of reproducibly creating highly aligned DNA nanowires without any surface modifications or special equipment. Stretched DNA molecules initially present on the PDMS sheet were transferred onto another surface using transfer-printing (TP). Fluorescent microscopic and atomic force microscopic images revealed that many DNA molecules were highly aligned on surfaces after TP. Furthermore, it was also possible to realize the two-dimensional assembly of DNA nanowires by repeating TP.

Imaging saponin-induced structural changes in neural processes with atomic force microscopy.

Temporal changes in the structure of neuronal processes in the presence of saponin were studied by atomic force microscopy in a fluid medium. After saponin treatment, concavities were formed on the surface of some neurites and fibrous structures in other neurites were splayed. The vertical height of these splayed fibrils or fibrillar bundles ranged from 13 to 370 nm, and the horizontal width was less than 500 nm. These findings suggest that formation of concavities and separation of bundled fibrils occurred simultaneously in saponin-treated neurites.
