Research Abstract |
We have developed frequency modulation atomic force microscope(FM-AFM) with a capability of irradiating a focused mid-infrared light from the bottom of the sample using a flat-type scanner with a hollow at the center. We have also achieved a significant improvement in the FM-AFM force sensitivity using a small cantilever to detect a subtle change in the surface property caused by the irradiation of an infrared light. We have demonstrated the molecular recognition capability of the developed microscope by imaging a phase-separated polystyrene-PMMA block copolymer thin film.
