Microfluidics Module

New App: Red Blood Cell Separation

This app examines the separation of red blood cells and platelets in a microfluidic channel using dielectrophoresis. The red blood cell and platelet diameter are input, as well as the electromagnetic frequency and applied potential. The separation efficiency is computed and there are visual plots for the particle trajectories, electric potential, and fluid velocity.

Red blood cells and platelets are separated by a dielectrophoretic force. The bottom-right outlet in the geometry only releases red blood cells, indicating that the sample is sufficiently pure for further analysis.

Part Library

Microfluidics simulations often include flows mixing or reacting in microfluidic channels. Furthermore, these simulations often model the effect of small changes on similar geometries, such as the length of the channel or the number of channel bends. In order to facilitate fast and efficient simulation of microfluidics channels, the Microfluidics Module includes a Part Library with a set of predefined geometry components representing some common channel configurations.

All microfluidic channel parts are modularized (parameterized) through a number of input parameters corresponding to important geometrical properties of each part. These can be adjusted in order to fit the geometries to the microfluidic system that is under investigation.

Examples of the serpentine, cross, and y-channels with square or circular cross sections. Some of the adjustable inputs are shown for the channels. Examples of the serpentine, cross, and y-channels with square or circular cross sections. Some of the adjustable inputs are shown for the channels.
