Direct visualization of nano- and micrometer-sized objects is the most straightforward way for their analysis in surface and polymer science, biomaterial research, and biology. Rapid progress in engineering and microtechnology has led to numerous techniques that allow observation and mechanical manipulation of microscopic objects of various natures. AFM [52] is the most commonly used of these techniques. In AFM, a sample surface is mechanically scanned with a tiny probe—a sharpened stylus fixed at the end of a flexible cantilever. When the stylus interacts with the samples, the resulting force acts on the stylus and causes deflection of the cantilever. This deflection is detected via an optical lever system, that is, a laser beam reflected from the end of the... 

Hiroshi Fukumura received his M.Sc and Ph.D. degrees from Tohoku University, Japan. He studied biocompatibility of polymers in the Government Industrial Research Institute of Osaka from 1983 to 1988. He became an assistant professor at Kyoto Institute of Technology in 1988, and then moved to the Department of Applied Physics, Osaka University in 1991, where he worked on the mechanism of laser ablation and laser molecular implantation. Since 1998, he is a professor in the Department of Chemistry at Tohoku University. He received the Award of the Japanese Photochemistry Association in 2000, and the Award for Creative Work from The Chemical Society Japan in 2005. His main research interest is the physical chemistry of organic molecules including polymeric materials studied with various kinds of time-resolved techniques and scanning probe microscopes.
