Electronically controlled µ-fluidic gradient systems

MICROFLUIDIC GRADIENT CHIP

Design & Principle

Mask design of an electronically controlled continuous flow reactor for spatial resolution of concentration and temperature gradients. Gradients in temperature (vertical) and concentration ratio of two fluids (horizontal). The blow-up image shows the electroosmotic driven membrane structures at the T-junction.

The electronically controlled µ-fluidic gradient chip is the improved version of microsystems for phase space screening we built up.


The resulting chip based of our Chemical Microprocessor ChµP platform achieves a linear temperature gradient (60°C > T > 5°C) across the microfluidic chip in one dimension as well, and a tunable (12  steps) concentration gradient generated along the second spatial direction, as a result of electronically generated material transport using BioMIPs electroosmotic driven membranes at the T-junctions of the meander structures.
