Outline of Final Research Achievements

A high sensitivity and high resolution photothermal microscopy was developed for imaging of tiny amount of chromophore molecules in a medium. Using the microscope, we studied physical properties of soft matter by measuring thermal diffusion process in agarose gel in nano-scale and motion of individual nanoparticles embedded in the gel. From this, the relation between thermal diffusion process and micro-scale movement of soft matter induced by heat was investigated.
