Infrared (IR) spectroscopy is a common method for the chemical characterization of organic and inorganic materials, but traditional FTIR techniques are limited in resolution and sensitivity on the order of several microns. Photothermal AFM-IR (or just AFM-IR) uses an AFM probe to detect thermal expansion of a highly localized area of material, resulting in a lateral resolution 1000x better than traditional FTIR, <1 nm detection sensitivity, and model-free interpretation.

Infrared (IR) spectroscopy is a commonly used characterization technique for organic materials and many inorganic compounds and crystals. While powerful, it is limited by the diffraction limit to resolution on the order of several microns, and the lateral resolution is strongly dependent on the wavelength.
Photothermal AFM-IR is a novel technique which offers IR spectroscopy and imaging on materials with a lateral resolution 1000x better than traditional FTIR and <1 nm detection sensitivity with model-free interpretation. AFM-IR achieves this by using an AFM probe as the detector of photothermal expansion. This opens a variety of applications on both organic and inorganic materials where nanometer sensitivity and resolution are key.
In this webinar, Bruker experts introduce the photothermal AFM-IR technique in depth, from working principles to applications, ending with a demonstration on the Dimension IconIR system.
