Title (EN) MANIPULATION OF PARTICLES IN LIQUID MEDIA
(FR) MANIPULATION DE PARTICULES DANS DES MILIEUX LIQUIDES
Abstract:
(EN) In a method of manipulating particles suspended in a liquid medium, a moving standing wave ultrasonic vibration and an electrical field capable of generating a dielectrophoretic force on the particles are applied. The ultrasonic vibration may be applied to move the particles from a first suspending liquid to a second suspending liquid, or to move the particles into proximity with electrodes to apply the dielectrophoretic force, or to move the particles into the centre of the liquid medium. Alternatively, the ultrasonic vibration and the electrical field may be applied simultaneously.
(FR) Dans un procédé de manipulation de particules en suspension dans un milieu liquide, une vibration ultrasonore dynamique à onde stationnaire et un champ électrique pouvant générer une force diélectrophorétique sur les particules sont appliqués. La vibration ultrasonore peut être appliquée pour déplacer les particules d'un premier liquide en suspension vers un second liquide en suspension. Elle peut aussi être appliquée pour déplacer les particules vers le voisinage d'électrodes afin d'y exercer ladite force diélectrophorétique, ou encore pour déplacer les particules vers le centre du milieu liquide. Dans un autre aspect, la vibration ultrasonore et le champ électrique peuvent être appliqués simultanément.
