Abstract :
Linear Brownian motors utilize relatively weak electric fields to bias the diffusion of particles in a microfluidic channel thereby harnessing Brownian motion to facilitate particle transport. We present a custom simulator for such a system and use it to optimize transport by modifying the electrode configuration and rectification scheme. With insight gained from simulation, we are able to identify features of potential energy profiles conducive to faster transport and suggest configurations to achieve them.
