A microscopic object detection system includes a collecting kit and a detection device. The collecting kit has a thin film for converting light into heat and is configured to be capable of holding a sample on the thin film. The detection device detects a plurality of microscopic objects in the sample by collecting the plurality of microscopic objects dispersed in the sample with the collecting kit. The detection device includes a laser module, an optical receiver, and a controller. The laser module emits a laser beam with which the collecting kit is irradiated. The optical receiver detects the laser beam from the sample held by the collecting kit and outputs a detection signal thereof. The controller calculates an amount of the plurality of microscopic objects collected in the sample based on a change of the detection signal over time.

Microscopic object detection device, detection system, and detection method

A method of collecting resin beads includes first to fourth steps. The first step is a step of preparing a sample on a thin film provided on an upper surface of a substrate. The second step is a step of irradiating the thin film with a laser beam and a laser beam with the laser beam and the laser beam being distant from each other. The third step is a step of producing a microbubble at a position irradiated with the laser beam and producing a microbubble at a position irradiated with the laser beam, by heating the sample by irradiation with the laser beams. The fourth step is a step of collecting a plurality of resin beads in a region between the microbubble and the microbubble by producing convection of the sample in a direction perpendicular to a direction of alignment of the microbubble and the microbubble.

Microscopic object collection method and microscopic object collection system

A laser module includes a plurality of light emission regions and the plurality of light emission regions emit a plurality of laser beams. An optical waveguide and a lens condense the plurality of laser beams to an identical focal point. An adjustment mechanism is configured to adjust relative positional relation between the sample stage and a condenser lens (the optical waveguide and the lens). A controller is configured to switch between a single-point irradiation mode and a multi-point irradiation mode. The single-point irradiation mode refers to a mode in which the adjustment mechanism is controlled such that the focal point of the plurality of laser beams falls on the thin film. The multi-point irradiation mode refers to a mode in which the adjustment mechanism is controlled such that the focal point does not fall on the thin film.
