Near-field microscopy has been applied to imaging of the fluorescent molecules, mapping of photo luminescence from quantum dots, and profiling of nanostructures with use of various types of near-field probes. In this presentation, we describe our research activities to observe molecular distribution by exciting the molecular vibration with use of a field-enhancing metallic probe. The principle, the instrumentation and the experimental results will be shown.
