Abstract

Janus particles are composed of two fused hemispheres of different substances. Such an anisotropic structure results in different trapping characteristics under a focused laser beam. In this paper, we show the axial and transversal trapping forces of Janus particles under a focused laser beam and discuss the conditions that would result in stable trapping. We also show the performed experiments and the applied numerical simulations using the Finite Difference Time Domain method.
