AFM/Raman - NEW

Integrated AFM/Raman instrument: Ntegra-Spectra (NT-MDT)

This is a recently acquired instrument purchased with the NRI support.

Ntegra-Spectra is the AFM/Raman instrument combining high resolution AFM imaging capabilities with the structural characterization of the sample down to single molecule level with Raman spectroscopy. Both AFM and Raman spectroscopy methods are non-invasive label-free approaches. The AFM/Raman instrument is capable of measuring spectroscopic properties of a sample simultaneously with the topographic image in the absence of labeling or contrasting. Ntegra-Spectra is optimized for Tip-Enhanced Raman Scattering (TERS). The TERS capability is provided by the use of special AFM tips terminated with a metal nanoparticle (usually gold or silver). Due to the nanometer size of the probe, the excitation of the sample occurs in the nanometer range, providing structural (Raman spectroscopy) analysis of the sample with spatial resolution of a few nanometers.

The instrument is installed at COP 1021.  Anyone who wants to use this instrument should contact Yuri Lyubchenko (ylyubchenko@unmc.edu) or Alexey Krasnoslobodtsev (akrasnos@unmc.edu) prior to planning the experiments.
