Presentation

The Center for Nanobiophotonics And Laser Microspectroscopy develops an interdisciplinary research focused on the fabrication and biofunctionalization of noble metal, semiconductor and polymer nanoparticles and hybrid nanostructures that perform novel function in nanophotonics and plasmonics with the aim of enabling novel spectroscopic and plasmonic-oriented applications. Noble-metal nanostructures (Ag, Au) exhibit strong interaction with the visible light due to the excitation of collective electron oscillations (localized surface plasmons) and, on the other hand, can bind specifically to many biological entities (biomolecules, proteins, cells, bacteria).

Currently, we study the interactions between nanostructures and biological entities with standard optical spectroscopy (uv-visible, Raman, fluorescence) and advanced methods based on scanning confocal Raman microscopy, surface-enhanced Raman spectroscopy (SERS), surface-enhanced IR absorption (SEIRA), confocal reflectivity and fluorescence, localized surface plasmon resonances (LSPR), dark-field microscopy in combination with Atomic Force Microscoopy AFM.
