Photothermal AFM-IR combines atomic force microscopy and infrared spectroscopy to reveal chemical heterogeneity and structural features at the nanoscale.

Photothermal AFM-IR technology provides spatially resolved infrared spectroscopy for detailed compositional mapping of ...

With Raman microscopy, there's an additional layer of complexity: fluorescence. Particle fluorescence can overwhelm the Raman signal and make routine analysis more challenging. In comparison, IR ...

Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of monochromatic light. Because different ...

Nuclear magnetic resonance (NMR) spectroscopy is a technique that detects the chemical environment of atomic nuclei by the absorption of radio-frequency electromagnetic radiation when in the presence ...
