Participating
countries and international organizations:
Armenia, Belarus, Bulgaria, Cuba, Egypt, Poland, Romania, Russia, Slovakia, Ukraine, Uzbekistan.
Issues
addressed and main goals of research:
Fundamental and applied research in the field of spontaneous and nonlinear Raman microspectroscopy aimed at highly sensitive biosensing. Study of mechanisms and nature of surface-enhanced Raman scattering (SERS) taking into account the anomalous ratio of line intensities in the anti-Stokes and Stokes spectral regions. Development of ultralow-frequency Raman spectroscopy for biomedical purposes, including early diagnostics.
Expected
results in the current year:
Development of a technique for simultaneous registration of Stokes and anti-Stokes components in SERS spectra.
Revealing a possible nonlinear dependence of SERS spectra on the pump power.
Detailed characterization of Raman spectra of liposomes with embedded proteins.
Search and identification of the Raman marker of NETosis for the purposes of early diagnostics.
Acquisition and registration of spectra using optics adapted for low-frequency Raman spectroscopy.
