Leveraging AM-FM Viscoelastic Mapping Mode, Cypher™ and MFP-3D™ atomic force microscopes (AFMs) lets users image viscoelastic properties, including storage modulus and loss tangent, with nanoscale spatial resolution. Nanomechanical imaging technique operates at 2 cantilever resonances simultaneously. First resonance is used for tapping mode imaging, or amplitude modulation (AM), while higher resonance mode is operated in frequency modulation (FM).
