Measurement surface plasmon polariton assisted optical force using a carbon nanowhisker mechanical resonator

Abstract

Optical tweezers are widely used for manipulating nano- and micro sized particles. The presence of a special plasmon substrate can significantly affect the optical forces acting on an object. This paper discusses the possibility of experimental measuring optical plasmon forces using a mechanical resonator based on a carbon nanowhisker. A mathematical model describing the effect of optical forces on nanowhisker oscillations with an additional nanoparticle at the end is presented with taking into account the effect of surface plasmon waves on the substrate.
