From: Remotely excited Raman optical activity using chiral plasmon propagation in Ag nanowires
The structure of the Ag nanowires and the propagation of surface plasmons in the Ag nanowires. (a) Structure of the Ag nanowires. (b) Surface plasmons propagating in the Ag nanowires. (c) Optical image of a single nanowire and evidence of the chiral propagation of surface plasmons in the Ag nanowires. The chirality can be manipulated by the polarization of the laser.
