Resonance Enhanced Force Volume AFM-IR: A Powerful New Technique for Nanoscale IR Characterization

Webinar Summary

Nanoscale infrared microscopy enables label-free, chemical imaging and spectroscopy at the nanometer scale by combining atomic force microscopy (AFM) with infrared radiation. Over the years, different AFM-IR modes have been developed: The original photothermal-induced resonance enhanced mode and surface sensitive AFM-IR are based on contact mode, while Tapping AFM-IR is built on tapping mode. All of these nanoIR variations, however, have the inherent advantages and limitations of their respective AFM base mode.

Resonance Enhanced Force Volume (REFV) AFM-IR is a novel approach that relies on off-resonance tapping to simultaneously capture nanomechanical and nanochemical properties and deliver previously inaccessible insights into material properties.
