Abstract
A microfluidic mixing device comprising two bellows pumps (), microfluidic cartridges comprising the same and methods for use of the same are provided. The disclosed device enables efficient mixing of samples at the microfluidic scale. More particularly, the microfluidic mixing device comprises: a first bellows pump (); a second bellows pump (); a first microchannel fluidly interconnecting the first bellows pump () with a sample inlet and a reagent reservoir, wherein the first microchannel comprises a valve (V) interposed between the pump and the inlet, and a valve (V) interposed between the pump and the reservoir; a second microchannel fluidly interconnecting the first bellows pump () with the second bellows pump (), wherein the second micro channel comprises a valve (V) interposed between the first and second pump; a third microchannel fluidly interconnecting the first bellows pump () with the second bellows pump, wherein the third micro channel comprises a valve (V) interposed between the first and second pump; a first and second pneumatic member pneumatically connected to the first and second bellows pumps; wherein, the volume of the second bellows pump () is greater than the volume of the first bellows pump ().
