Abstract

L'invention concerne un dispositif pour mesurer les caractéristiques de membranes de vésicules, comprenant un récipient contenant des ions lipophiles et les vésicules et une électrode sélectivement sensible aux ions lipophiles. Selon l'invention, une unité arithmétique 37 est électriquement connectée à l'électrode 13 pour calculer le taux de changement avec le temps de la sortie de l'électrode. L'invention s'applique notamment aux recherches biomédicales.
