Abstract

In this work we explore the possibility of developing micro-/nano-fluidic devices which exploits the intense electromagnetic fields present in nanophotonic structures as the primary transport mechanism. This transport mechanism is based on exploiting the near-field optical gradients (which serve to confine particles through a Lorenz force) and concentrated optical energy (resulting in intense scattering and absorption forces for propulsion through photon momentum transfer) present in these devices to perform a series of particle handling operations including transport, concentration and separation. Nanophotonic transport offers unique properties which give it several advantages over traditional techniques including: favorable transport scaling laws, extremely strong velocity dependence on particle size, insensitivity to surface/solution conditions and indefinitely long interaction lengths. In this work we detail the theory behind photonic transport and outline in detail the major advantages. Some of our initial experimental results on transport in liquid core photonic crystal devices and developing numerical simulation techniques describing photonic transport in such devices.
