dispensing subtitled

Digital microfluidic device manufactured at the Emerging Communications Technology Institute (ECTI), University of Toronto, by Prof. Aaron Wheeler’s research group. The device dispenses 70-nanolitre droplets from reservoirs and then moves, merges, and mixes them by applying a sequence of voltages to an array of electrodes. Duration : 0:0:5

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 […]
