    Abstract: The present invention provides a method of analyzing a sample containing an analyte to be qualitatively and/or quantitatively determined, comprising a binding step and a washing step, wherein the binding step comprises: interacting the analyte with beads having a density m1; obtaining a structure of packed beads comprising quantifiable bead complexes having a density m2; and the washing step comprises: dispersing the packed beads in a liquid medium having a density d>m2 and m1; and separating the liquid medium and the beads comprising the quantifiable bead complexes.

    Abstract: A method for transferring beads in a fluidic chip having an internal fluid circuit through which various reactants, including beads, may be moved by use of centrifugal force includes providing beads having a density equal to, or lower than, m1 in a section of the fluid circuit, where the section includes at least a first outlet. The method includes providing a first liquid medium having a density d2 to the section, such that d2>m1, and applying a centrifugal force such that the beads migrate in an opposite direction of the centrifugal force.
