Previous and Current Research

Research in area of the light-matter coupling in metal-based hybrid nanostructures occurring at the excitation of localized and propagating surface plasmons, with the aim of practical use in sensorics, nanophotonics and biomedical applications.

1.   The hybridization of the surface plasmon mode of the layer of metal nanoparticles and the plasmon polariton mode of the metal film was revealed for the monolayer of Au nanoparticles / dielectric interlayer / Al film planar cavity nanosystem, which leads to the formation of a collective plasmon gap mode, Figs. 1, 2. The variation of the cavity parameters as well as polarization and angle of incidence of light makes it possible to controllably adjust the plasmonic enhancement factor and the spectral range of extinction and light emission by molecular emitters located in such nanocavity. Such possibility makes such nanocavities to be promising for use in the novel nanophotonic devices.

2.   The plasmonic metasurfaces based on laser-structured Ag surfaces (LIPSS) and Au nanorods and Ag nanoprisms were developed to provide huge plasmonic enhancement of the photoluminescence of adenosine nucleotide biomolecule applied to such metasurfaces by more than three orders of magnitude at room temperatures, Fig. 3. The prospects of using such plasmonic metasurfaces for highly sensitive luminescent detection of biomolecules at room temperature without the addition of luminescent labels were proven.

3.   The thermoresponsive Zinc TetraPhenylPorphyrin photosensitizer / Dextran poly (N-isopropylacrylamide) graft copolymer / Au Nanoparticles (ZnTPP/D-g-PNIPAM/AuNPs) triple hybrid nanosystem was synthesized in aqueous solution as a nanodrug for potential use in thermally driven and controlled photodynamic therapy applications, Fig. 4. The 2.7-fold enhancement of singlet oxygen photogeneration under resonant with surface plasmon resonance has been observed for ZnTPP/D-g-PNIPAM/AuNPs proving the plasmon nature of such effect. The data obtained in vitro on wild strains of Staphylococcus aureus have proved the high potential of such nanosystem for efficient rapid photodynamic inactivation of microorganisms in particular in wounds or ulcers on the body surface.

Future Projects and Goals

1.   The study of the light-matter coupling and plasmonic gap excitation in plasmonic cavity based metasurfaces. The use of generated highly intense local plasmonic field in cavity for huge enhancement of the optical processes in molecules (biomolecules in particular) located on such metasurfaces in sensor applications.

2.   The study of thermosensitive polymer / metal nanoparticles / dye molecules hybrid nanosystems in aqueous solutions for potential use as thermoresponsive fluorescent optical switch and label.

3.   The development and study of aqueous colloidal solutions of Au(Ag) nanoparticles / polymer / photosensitizer hybrid nanosystems with increased efficiency of singlet oxygen generation for use in photodynamic therapy applications.

4.   The study of the plasmonic enhancement of the photoluminescence and Raman scattering of 2D transition metal dichalcogenides in layered hybrid nanostructures containing non-spherical metal nanoparticles.
