Microfluidics T-junction CFD

This is a run of the example microfluidics T-junction simulation in elmer, an open source CFD/FEM/FEA package. What you see here is the progression of an analyte due to electro-osmotic flow. There are two electric fields, three boundary conditions and a lot of wasted hours playing around with ElmerGUI and ElmerFront. Duration : 0:0:4

U type 1 hole for trapping cells

Using 3T3 cells as a model system, the motion of each individual cell was calculated using a one-way coupled Lagrangian method. The cell was assumed to be a solid sphere, and interactions with other cells were only considered when a cell sedimented in the trap. The ordinary differential equations were solved along the cell trajectory […]

flat type seive for trapping cells

The “flat-type sieve” consists of an array of nine sieves arranged in a symmetric diamond-shaped pattern. Under simulated conditions, sieves closer to the chamber entrances captured cells well for both geometries, while the downstream sieves remained empty. related article: Building a Better Cell Trap: Applying Lagrangian Modeling to the Design of Microfluidic Devices for Cell […]
