Abstract: An analysis method for identifying and counting particles expressing a specific antigenic marker is proposed. One example (but not exclusive) is CD4+ T-lymphocyte analysis in blood. The method comprises obtaining a sample comprising particles in suspension, labeling the particles expressing the specific marker with an impedance label, and measuring the labeled sample using a dual frequency system to discriminate at least the labeled particles expressing the specific marker. The method allows an accurate count of particles e.g. the number CD4+ T-lymphocytes in a blood flow. A corresponding device is also provided.

Abstract: An electro-optic display comprising at least two separate layers of electro-optic material, with one of these layers being capable of displaying at least one optical state which cannot be displayed by the other layer. The display is driven by a single set of electrodes between which both layers are sandwiched, the two layers being controllable at least partially independently of one another. Another form of the invention uses three different types of particles within a single electrophoretic layer, with the three types of particles being arranged to shutter independently of one another.

Abstract: The object of this invention is to provide a method by which to form molecule recognizing films on sensor electrodes efficiently, within a short period, uniformly and in a high quality state. Another object of this invention is to provide a method by which to accurately introduce a vast number of biological samples for evaluation to the plural minute sensor electrode dots within a short period and efficiently. In order to form organic thin films on electrodes, a solution of a material for the organic thin film is accurately printed via an ink-jet onto the surface of microelectrodes as required, thereby producing a high density array of microelectrodes. Further, a solution of a sample substance or a liquid substance to be sensed is ejected into air via an ink-jet nozzle to fall to the surface of organic thin membranes on the microelectrodes so that the sample is evaluated.
