Abstract:
We report on the functionalization of nanocrystalline $nc$-Si/SiO$_2$ semiconductor quantum dots (QDs) by short d(20G, 20T) oligonucleotides. The obtained complexes have been studied by Raman spectroscopy techniques with high spectral and spatial resolution. A new phenomenon of multiband resonant light scattering on single oligonucleotide molecules has been discovered, and peculiarities of this effect related to the nonradiative transfer of photoexcitation from $nc$-Si/SiO$_2$ quantum dots to d(20G, 20T) oligonucleotide molecules have been revealed.
