| Outline of Final Research Achievements |
We demonstrated visualization of Au and polystyrene (PS) nanoparticles buried in polymer matrices using a newly developed technique, scanning thermal noise microscopy (STNM), in which the thermal noise spectra of a cantilever is recorded at each pixel while the tip is scanned over the surface. The contact resonance calculated from the thermal noise spectrum clearly showed the features of the Au and PS nanoparticles.
