We kindly invite you to join us for this live webinar: An Introduction to Nanoscale Infrared Spectroscopy and Imaging with Photothermal AFM-IR.

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.

• Introduce the photothermal AFM-IR technique
• Explore the surprisingly simple mechanism underlying the technique
• Highlight a few of its many broad applications
• Offer a demonstration of photothermal AFM-IR on the Dimension IconIR system
