Abstract

Gold nanoparticle mediated laser stimulation of neuronal cells allows for cell activation on a single-cell level. It could therefore be considered an alternative to classical electric neurostimulation. The physiological impact of this new approach has not been intensively studied so far. Here, we investigate the targeted cell’s reaction to a laser stimulus based on its calcium response. A complex cellular reaction involving multiple sources has been revealed.
