The research group focuses on the design, fabrication, and characterization of plasmonic nanomaterials, with particular emphasis on gold nanoparticles with controlled morphology and surface functionalization. The conducted studies include the analysis of their optical and photothermal properties, as well as their interactions with electromagnetic radiation in single- and multicomponent systems. An important area of the group’s activity is the controlled organization of nanoparticles into ordered structures at phase interfaces using Langmuir techniques and layer-transfer methods onto solid substrates.
The group’s research combines experimental investigations with theoretical modeling, enabling a comprehensive understanding of the mechanisms underlying observed phenomena such as plasmon hybridization and the Surface-Enhanced Raman Scattering (SERS) effect. In parallel, functional nanoplatforms are being developed for applications in molecular detection and biospectroscopy, with a focus on their further optimization and practical implementation.
