Abstract
We had developed a scanning near-field middle-infrared microscope, based on AgClBr probes, which has a subwavelength resolution in air. We adapted this microscope for imaging of samples submerged in water. Toward this goal, we had to develop a theoretical model for the mechanical vibration of the probes in water and use it for the construction of an improved microscope. Using this system, we obtained infrared and topographic images of polymer beads of subwavelength diameters. This microscope will be particularly useful for high resolution spectral imaging of living biological cells in the middle infrared.
