Abstract:
Methods and devices for concentrating target cells using dielectrophoresis (DEP) are disclosed. The method allows relatively high throughput of sample through a microfluidic device in order to allow rapid capture of target cells even when they are present in low concentrations within the sample. The method utilizes multiple chambers through which samples will flow, the chambers arranged such that the first capture area has a larger area and faster flow rate than a second chamber, the second chamber being positioned downstream of the first capture area and being smaller with a slower flow rate to further concentrate the material captured in the first capture area.

Claim (Index 27):
A microfluidic device for concentrating target particles, such as target cells, in a sample, comprising;\n a first capture area, the first capture area comprising a first means for selectively and releasably capturing target particles, said means arranged such that a sample flowing through the first capture area will flow over said means; a second chamber, downstream of the first capture area and in fluid communication therewith, the second chamber being of smaller volume than the first capture area and comprising a second means to capture target particles arranged such that a sample flowing through the second capture area will flow over said means; a control module; flow control means to allow flow rate through the second chamber to be lower than the flow rate through the first capture area.
