Claim Text:
1. A centrifugal force based microfluidic system for the automated analysis of samples containing at least one analyte involving the use of magnetically responsive particles which interact with said analyte, said system comprising: at least one rotatable supporting device; at least one microfluidic device directly fixed to said supporting device so as to rotate therewith and provided with at least one microfluidic structure having at least one inlet zone, at least one reaction chamber which receives one of said samples and which is in fluid communication with said at least one inlet zone comprising at least a first retention zone and a second retention zone in fluid communication with said first retention zone which retain said magnetically responsive particles; at least one first magnet directly fixed to said supporting device in correspondence to said at least one first retention zone so as to rotate therewith and to generate a magnetic field which retains said magnetically responsive particles in said first retention zone; and at least one second magnet directly fixed to said supporting device in correspondence to said at least one second retention zone so as to rotate therewith and to generate another magnetic field which retains said magnetically responsive particles in said second retention zone.
