A method of mixing magnetic particles (3) in a reaction chamber (2) that is part of a microfluidic device and that contains the said particles in suspension, comprises the steps: (a) providing an electromagnetic means (1,1 ',6, 7) to generate magnetic field sequences having polarity and intensity that vary in time and a magnetic field gradient that covers the whole space of the said reaction chamber (2); (b) applying a first magnetic field sequence to separate or confine the particles (3) so the particles occupy a sub-volume in the volume of the reaction chamber (2); (c) injecting a defined volume of the said reagent in the reaction chamber; and (d) applying a second magnetic field sequence to leads the particles (3) to be homogenously distributed and dynamically moving over a substantial portion of the whole reaction chamber volume.

L'invention concerne un procédé permettant de mélanger des particules magnétiques (3) dans une chambre de réaction (2) faisant partie d'un dispositif microfluidique et qui contient lesdites particules en suspension. Le procédé consiste: (a) à fournir un élément électromagnétique (1, 1', 6, 7) pour produire des séquences de champs magnétiques dont la polarité et l'intensité varient dans le temps et un gradient de champ magnétique qui couvre l'ensemble de l'espace de ladite chambre de réaction (2); (b) à appliquer une première séquence de champs magnétiques afin de séparer ou de confiner les particules (3) de sorte que ces dernières occupent une partie du volume de la chambre de réaction (2); (c) à injecter un volume défini dudit réactif dans la chambre de réaction; et (d) à appliquer une seconde séquence de champs magnétiques pour amener les particules (3) à se répartir de manière homogène et à se déplacer de façon dynamique sur une grande partie de l'ensemble du volume de la chambre de réaction.
