| Research Abstract |
Viscoelasticity is a crucial idea for understanding dynamics of soft matters. Novel methods for obtaining frequency-resolved viscoelasticity of nanometer-scale soft-matter systems like polymers or liquid solvation were developed based on atomic force microscopy(AFM) having an ultimate spatial resolution. A frequency-domain method utilizing multiple resonance modes of the AFM force sensor and a time-domain method in which resonances of the force sensor are suppressed were developed.
