Erik Martinsson (Ph.D.)


My research is focused on metal nanoparticles and how they can be used for sensing applications. Metal nanoparticles can create localized surface plasmon resonance when exposed to light at a specific frequency (Fig 1). This creates a collective oscillation of the electrons in the nanoparticles where the frequency is highly dependent on the size and the structure of the particles, their interaction with other particles and the dielectric properties of the surrounding medium (Fig 2).

Fig 2: Schematic illustration showing the basic concept behind nanoplasmonic sensing based on refractometric detection. A shift of the plasmon peak position is observed in the extinction spectra when an analyte interacts with a ligand on the surface of a metal nanoparticle.
