Abstract
A microfluidic device for concentrating particles in a concentrating solution. A sample and a concentrating fluid flow laminarly with a microfluidic channel wherein the concentrating fluid is formulated such that it extracts fluid from the sample and thus concentrates the particles in the sample.
Claims7
A microfluidic device, comprising:
- a first and second inlet connected to a first and second inlet channel;
- a main channel connected to said first and second inlet channels;
- a concentrating fluid flowing into said first inlet channel;
- and a sample fluid containing a first type of particles distributed in said sample fluid flowing into said second inlet channel,
- wherein said concentrating fluid and said sample fluid flow in parallel in said main channel such that said fluids form a fluid interface across which sample fluid molecules diffuse into said concentrating solution such that the concentration of said first type of particles in said sample fluid is increased.

A microfluidic device, comprising:
- a first and second inlet connected to a first and second inlet channel;
- a main channel connected to said first and second inlet channels;
- a first fluid flowing into first said inlet channel;
- and a second fluid containing a first and a second size of particles distributed in said sample fluid flowing into said second inlet channel,
- whereas the average flow speed of said first fluid is different from the average flow speed of said second fluid.
