Flow morphing through flux-flow interaction in a deterministic lateral displacement bio-microfluidic device
Through numerical experiments involving fluid flow and electromagnetic fields, this paper aims to investigate the impact of an external electrokinetic field (EF) on the deterministic lateral displacement (DLD) microfluidic sorting technique that occurs in a biochip. The Constructal Law (CL) operates naturally in this context through the physics of the intrinsic couplings between microfluidic flow and the external EF, which can be tuned by the experiment designer, who is empowered to promote electrophoresis-controlled DLD by adjusting the applied voltage. We observe, as stated by the CL, that fluxes shape the flow of particles and their separation in the DLD device.
