The morphologies of pure buffer solution and DNA-containing solution in an open fluidic channel with rectangle cross section (1 microm in width and 150 nm in depth) have been explored using non-contact AFM. A remarkable feature is that a uniform nano-scale trench (approximately 15 nm deep and 14 microm long) on the surface of the DNA solution has been(More)
