Abstract
A microfluidic device for separating emulsion solution into separate particles by passing the emulsion solution through a passive filter. The separated particles can then be sorted into separate chambers through active filtering.
Claims23
A microfluidic device for separating an emulsion, comprising:
- a baseplate layer;
- a flow layer attached to the baseplate layer;
- a control layer attached to the flow layer, such that the baseplate layer, the flow layer, and the control layer form the microfluidic device;
- a first section and a second section;
- a microfluidic channel within the flow layer, the microfluidic channel passing through the first section and the second section, and configured to flow the emulsion therein;
- a first filter located within the first section, the first filter configured to separate the emulsion into desired particles and undesired particles;
- and
- a second filter located within the second section, the second filter configured to sort the desired particles and send each desired particle into a predetermined channel.
