Abstract
Method and system for carrying out heterogeneous chemical or biological reactions are disclosed. The method comprising providing an analytical device having at least one liquid processing unit having at least one reaction chamber and a first inlet channel in fluid communication with the reaction chamber. The method further comprises supplying to the reaction chamber via the first inlet channel or a second inlet channel analyte capturing particles, supplying to the reaction chamber via the first inlet channel or the second inlet channel a liquid sample containing an analyte of interest, and confining by an equilibrium of forces the analyte capturing particles in a particle rearrangement zone within the reaction chamber. The forces comprise a drag force Fd generated by flowing liquids and a counter-oriented force Fg. The method also comprises capturing analytes present in the liquid sample with the particles in the particle rearrangement zone.
