nano-FTIR measures characteristic IR spectroscopic signatures at the nanoscale
The combination of tapping-mode AFM technology and FT-IR spectroscopy ( nano-FTIR ) provides a unique tool to measure infrared absorption spectra of any AFM-ready biological sample with nanometer spatial resolution . nano-FTIR provides excellent correlation to conventional FT-IR spectroscopy data enabling detailed analysis of the measured absorption lines and bands .
