Abstract

Selon cette invention, un panneau électrophorétique (10) provoque la migration d'une substance diélectrique par application d'un champ électrique généré par une tension alternative, vers un échantillon contenant la substance diélectrique susmentionnée. Ce panneau électrophorétique (10) est équipé, sur un substrat inférieur (1), de plusieurs voies de migration (3) destinées à provoquer la migration diélectrique de la substance diélectrique. Sur le substrat inférieur (1) est situé un réseau d'électrodes de migration (6) contenant plusieurs électrodes de migration (6a) se croisant avec les voies de migration (3) et provoquant la migration diélectrique de la substance diélectrique par application d'une tension alternative de façon à appliquer le champ électrique à l'échantillon injecté dans les voies de migration (3). Au moins une partie des faces des voies de migration (3) opposées au réseau d'éléctrodes de migration (6) sont transparentes, au niveau des zones dans lesquelles les voies de migration (3) et le réseau d'électrodes (6) sont superposés. En outre, dans le réseau d'électrodes de migration (6), les électrodes de migration (6a) sont constituées au moins en partie d'électrodes transparentes au niveau des parties superposées aux parties transparentes des voies de migration (3).
