Abstract:
1. A method for carrying out heterogeneous chemical or biological reactions, the method comprising: providing an analytical device comprising at least one liquid processing unit, the at least one liquid processing unit comprising at least one reaction chamber and a first inlet channel in fluid communication with a corner of the at least one reaction chamber; providing analyte capturing particles in the at least one reaction chamber; supplying to the at least one reaction chamber via the first inlet channel or a second inlet channel a liquid sample containing an analyte of interest; confining by an equilibrium of forces and geometry of the at least one reaction chamber and the first inlet channel the analyte capturing particles in a particle rearrangement zone within the at least one reaction chamber, the forces comprising a drag force Fd, generated by liquids flowing through the first inlet channel by centrifugal forces or generated by liquids flowing induced by Euler forces within the reaction chamber, and a counter-oriented force Fg induced by a centrifugal force; and capturing analytes present in the liquid sample with the analyte capturing particles in the particle rearrangement zone.
