発明の名称 (英語) MICROOBJECT COLLECTING DEVICE, COLLECTING CONTAINER USED FOR SAME, AND MICROOBJECT COLLECTING METHOD NEW
発明の概要(英語) A bacteria (B) collecting device includes a laser light source (5) that emits laser light (L1), and a container (11) that is configured to be able to hold a dispersion liquid (D), in which a plurality of bacteria (B) are dispersed. The container (11) includes a bottom surface (111) and an inner surface (112). A thin film (12) that converts the laser light (L1) coming from the laser light source (5) into heat is formed on the bottom surface (111). On the inner surface (112), when coming into contact with the dispersion liquid (D), immersional wetting due to the dispersion liquid (D) occurs. The thin film (12) generates heat convection in the dispersion liquid (D) by heating the dispersion liquid (D). The inner surface (112) generates Marangoni convection at the gas-liquid interface, which is the interface between the dispersion liquid (D) and the gas around the dispersion liquid (D).
従来技術、競合技術の概要(英語) BACKGROUND ART
Microorganism or micro-fine particles by light irradiation such as the technology is integrated into the target position has been proposed.For example International Publication No. 2015/170758 (Patent Document 1) is described, for holding the liquid dispersed beads to the substrate by laser beam irradiation, the irradiation position of laser light (laser spot) disclose a technique that is integrated with the beads.
In more detail, according to Patent Document 1, samples (a plurality of beads dispersed in the dispersion) was dispensed onto the substrate, light energy is converted into thermal energy to the gold thin film is formed.Therefore, the gold thin film is irradiated with laser light, thermal energy can be converted into a liquid is heated, a temperature gradient is produced in the liquid.Thereby, heat convection occurs in the liquid.By using heat convection, the beads in the vicinity of the laser spot can be integrated (for example Patent Reference 1 of Fig. 1-see Fig. 6).
