Quantitative analysis by nanoelectromechanical photothermal infrared spectroscopy with picogram sensitivity

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate an advanced approach for quantitative spectral analysis of volatile chemical compounds with nanoelectromechanical infrared spectroscopy. We present high resolution infrared spectra of caffeine with a sensitivity of 7 pg obtained with SiN trampoline resonators.
