Abstract
This disclosure concerns a system with scattering analysis including a handling system that presents a single particle to at least one quantum cascade laser (QCL) source. The QCL laser source is configured to deliver light to the single particle in order to induce resonant mid-infrared absorption in the particle or an analyte within the particle. A mid-infrared detection facility detects the mid-infrared wavelength light scattered by the single particle, wherein a wavelength and angle analysis of the scattered mid-IR wavelength light is used to determine analyte-specific structural and concentration information.
