The present invention relates to a method and an apparatus for the characterization and/or the counting of particles by means of non uniform, time variable force fields and integrated optical or impedance meter sensors. The force fields can be of positive or negative dielectrophoresis, electrophoresis or electro-hydrodynamic motions, characterized by a set of stable equilibrium points for the particles (solid, liquid or gaseous); the same method is suitable for the manipulation of droplets (liquid particles) by exploiting effects known to the international scientific community with the name of Electro-wetting on dielectric. The aim of the present invention is to act on the control of the position of each particle which is present in the sample, for the purpose of displacing such particles in a deterministic or statistical way, in order to detect their presence with the integrated optical or impedance meter sensors and/or characterize their type, for the purpose of counting or manipulating them in an efficient way.

L'invention concerne un procédé et un dispositif de caractérisation et/ou de dénombrement de particules qui font intervenir des champs de forces non uniformes et variables dans le temps ainsi que des capteurs optiques ou impédancemétriques intégrés. Le champ de force peut être un champ de diélectrophorèse positive ou négative, un champ d'électrophorèse ou un champ de mouvements électro-hydrodynamiques, caractérisé par un ensemble de points d'équilibre stable pour les particules (solides, liquides ou gazeuses). Ce même procédé permet de manipuler les gouttelettes (particules liquides) par l'exploitation des effets connus par la communauté scientifiques internationale sous l'appellation : <= électromouillagesur diélectrique >=. Le but de l'invention est d'agir sur la position de chaque particule présente dans l'échantillon afin de déplacer l'ensemble des particules de manière déterministique ou statistique et détecter ainsi leur présence au moyen des capteurs optiques ou impédancemétriques intégrés, et/ou de caractériser leur type, à des fins de dénombrement ou de manipulation efficace.
