Abstract
(EN)
A magnetic platform is provided and includes a patterned array of discrete magnetic elements positioned on a substrate, a plurality of first electromagnets for creating a first magnetic field substantially in the plane of the substrate, an electromagnetic coil for creating a second magnetic field substantially perpendicular to the plane of the substrate, and a control device for controlling the application of the magnetic fields. Processes for manipulating, transporting, separating and sorting micro- or nano-scale particles and biomolecules are also described.

L'invention concerne une plate-forme magnétique qui comprend un réseau à motif d'éléments magnétiques discrets placés sur un substrat, une pluralité de premiers électroaimants pour créer un premier champ magnétique sensiblement dans le plan du substrat, une bobine électromagnétique pour créer un deuxième champ magnétique sensiblement perpendiculaire au plan du substrat, et un dispositif de commande pour commander l'application des champs magnétiques. L'invention concerne également des procédés de manipulation, de transport, de séparation et de tri de particules et de molécules biologiques à l'échelle microscopique ou nanoscopique.
