Title: Introducing nano-FTIR – imaging and spectroscopy at 10 nm spatial resolution

Abstract: Fourier-transformation infrared (FTIR) spectroscopy in the fingerprint region is an established

technique to characterize inorganic and organic materials. But conventional FTIR spectroscopy is

unsuited to measure with nanoscale spatial resolution due to the diffraction limit.

The NeaSNOM microscope together with its nano-FTIR spectroscopy module allows measuring

optical properties of samples with typically 10 nm spatial resolution. It employs an externally

illuminated sharp metallic tip which transmits the local information about the sample to the far

zone, where the FTIR spectra can be recorded.

Neaspecs patented broad-band illumination and background suppression technique eliminates

the diffuse light and thus allows a spatial resolution of 10 nm throughout the infrared spectrum.

nano-FTIR is equally suited for organic and inorganic samples and requires only standard AFM

sample preparation. An outlook of several applications of nanoscale chemical mapping by local

infrared imaging and spectroscopy will be presented.
