Synthesis and application of magnetoplasmonic nanoparticles for SERS analysis

Surface Enhanced Raman Spectroscopy (SERS) is one of the trending scientific field in the world, however it faces some challenges: surface contamination, poor signal reproducibility, or low analyte concentration. The hot spots created between closely packed silver or gold nanoparticles could be used for the determination of small analyte concentration if the latter is adsorbed on the metal surface. The aim of this PhD studies would be to synthesize core shell nanoparticles with magnetic core and plasmonic shell that would deal with two SERS challenges: 1) the analyte, adsorbed on the surface of magnetoplasmonic nanoparticle could be concentrated using external magnetic field; 2) the external magnetic field could be used to direct and precipitate the nanoparticles on the surfaces that normally they do not adsorb. Thus, the conducted PhD studies will significantly contribute in the field of Raman spectroscopy.
