Abstract: Provided is a technique for moving all of a droplet from a microchannel in which the droplet have been introduced to another layer.
The droplet transport device of the present disclosure includes a substrate having a through-hole or a recess, a first electrode provided on the substrate along the surface of the substrate and arranged at a position adjacent to the through-hole or the recess, a plurality of second electrodes provided on the substrate along a surface of the substrate and to which a voltage for moving the droplet introduced on the substrate is applied, and a dielectric layer covering the surface of the substrate, the first electrode, and the second electrodes, and a water-repellent film provided on the inner wall surface of the through-hole or the recess, and on the dielectric layer.

Abstract: Aiming at achievement of timely installation of the cartridge, sequential execution of the pretreatment process in the order of installation of the cartridge, and individual shifting of the process to the electrophoresis process upon completion of the pretreatment process, the electrophoresis device according to the present invention includes a plurality of capillaries each filled with a separation medium, a thermostat chamber for holding the capillaries at a predetermined temperature, an irradiation detector which executes light irradiation and detection in an electrophoresis process using the capillaries, a high voltage power supply unit for voltage application to the capillaries, a liquid feeding mechanism for feeding the separation medium to the capillaries, and an autosampler for conveying containers each holding a reagent or a sample to the capillary. The voltage application to the capillaries by the high voltage power supply unit is controlled for each of the capillaries.

Abstract: In a right-handed XYZ coordinate system, a dichroic-mirror array of the present disclosure includes a first group in which m (m≥2) dichroic mirrors DA1 to DAm are arranged parallel to each other along a positive direction of an X axis and a second group in which n (n≥2) dichroic mirrors DB1 to DBn are arranged parallel to each other along a negative direction of the X axis. Incident surfaces of the DA1 to DAm and incident surfaces of the DB1 to DBn are perpendicular to an XZ plane. A slope of straight lines with normal lines of the incident surfaces of the DA1 to DAm projected onto the XZ plane are negative, and a slope of straight lines with normal lines of incident surfaces of DB1 to DBn projected onto the XZ plane are positive.
