Modeling evaporation and ring-shaped particle deposition of a colloidal microdroplet, with applications in biological assays

Bhardwaj R., Attinger D., Columbia University, US

Colloidal drops evaporating on a solid substrate can be used as vehicles for dispensing or organizing small particles suspended within them. The pattern left after evaporation can be a ring-like structure such as the dried [...]

Numerical Simulation of Field Amplified Sample Stacking in Microfluidic System

Feng J.J., Krishnamoorthy S., Sundaram S., Bhardwaj R., Santiago J.G., CFD Research Corporation, US

In this paper we developed a numerical simulation method that solves the transport phenomenon associated with sample stacking in microchip-based separation system. The model is based on thin double layer approximation where the electrostatic force [...]
