title: Mid-infrared spectroscopy beyond the diffraction limit via direct measurement of the photothermal effect.
abstract: An atomic force microscope equipped with temperature sensitive probes was used to measure locally the photothermal effect induced by IR light absorption. This novel instrument opens a pathway to correlated topographical, chemical composition, and thermal mapping with nanoscale resolution. Proof of principle demonstration is provided on polymers and plasmonic samples.
