Abstract

Different allocations of nano-pillars were investigated for DNA electrophoresis separation. The square allocation shows that DNA was extended and moved straight without disturbance of pillars, but DNA entangled around pillars in the case of the tilt allocation. The tilt allocation allowed us to separate DNA of 10 kbp and 38 kbp by their sizes, whereas square allocation demonstrated one broad peak alone. The separation in the tilt nano-pillars pattern is considered to result from the sieving effect for different sizes of DNA. These results suggest that any disturbance is necessary for electrophoretic separation of small size DNA.
