Provided are a cell imaging device and a cell imaging method that can shorten the time period of taking images of cells in a liquid sample, compared with conventional techniques. This cell imaging device introduces a urine sample containing cells into an internal space of a sample cell, moves at least one of the sample cell and an objective lens in a second direction while at least one of the sample cell and the objective lens is moved in a first direction, the second direction being different from the first direction, and takes, at a plurality of imaging positions, images of cells contained in the urine sample by means of an imaging unit.

The invention is directed to a heated stage assembly that can achieve high temperatures (i.e., 40 degrees Celsius and higher and more specifically, 55 degrees Celsius and higher) for use in microscopy including fluorescence microscopy. The microscope stage heater assembly includes a mounting adapter element, a sample holder element mounted within the mounting adapter element, one or more heating elements attached to the sample holder element, and an optical window holder element disposed on a surface of the sample holder element that encloses an optical window element. The optical window element may be in contact with a microscope sample such that the optical window element is heated by the sample holder element to uniformly distribute heat to the specimen.

A microscope for microscopic examination of a sample includes an illumination optics for illuminating the sample, an imaging optics for imaging the sample, a sample chamber for receiving the sample. The sample chamber has a door providing access into the sample chamber. The microscope further includes a first fan assembly arranged on a first side of the sample chamber for blowing atmosphere into the sample chamber or for draining atmosphere out of the sample chamber, through at least one first opening arranged on the first side in a first side wall of the sample chamber, and at least one second opening arranged on a second side in a second side wall of the sample chamber for allowing atmosphere from inside the sample chamber to exit the sample chamber or for allowing atmosphere from outside the sample chamber to enter the sample chamber.

Systems for performing cellular analysis and related devices for conditioning environments adjacent chips in such systems. A device for conditioning an environment adjacent a chip in a system for performing cellular analysis, the device includes a cover for being disposed adjacent the chip and comprising a planar body having a top surface, a bottom surface, and an outer edge surface. The cover includes a central opening extending between the top surface and the bottom surface and bounded by an inner edge surface of the cover. The cover also includes a fluid inlet extending into the body from the outer edge surface between the top surface and the bottom surface the fluid inlet arranged to accept a gas to be delivered to the central opening. The cover also includes a plurality of fluid outlets defined in the inner edge surface and in fluid communication with the fluid inlet. The plurality of fluid outlets are arranged to receive the gas from the fluid inlet and exhaust the gas into the central opening.

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.

A particle beam apparatus and/or a light microscope is operated. A first temperature of an object may be changed, where the object may be arranged on an object receiving device rendered movable by a motor operated by a supply current. Changing the first temperature of the object may alter a second temperature of the object-receiving device from a first temperature value to a second temperature value. The supply current of the motor may be changed from a first current value to a second current value, where the supply current is designed to hold the object-receiving device in position, and a temperature of the object-receiving device may be changed from the second temperature value to a third temperature value on account of heat generated by the motor, which may be obtained by the second current value of the supply current and fed to the object receiving device.

Methods and systems of performing an assay. A system for performing an assay includes an enclosure defining a temperature-controlled space. An imaging system, an actuator and a dispenser are disposed within the space. The actuator receives a well plate having wells. The actuator is to move the well plate relative to the imaging system to enable the imaging system to obtain image data of one of the wells. The dispenser includes a pump, an outlet and a reservoir holder to receive a reservoir containing a compound. The pump is to be fluidly coupled to the reservoir and an outlet. The pump is to pump the compound from the reservoir through the outlet into one of the wells. The system also includes a controller. The controller is to cause the dispenser to dispense the compound into the first one of the wells while the imaging system obtains the image data.

A collecting apparatus for bacteria includes: a laser beam source configured to emit a laser beam; and a container configured to hold a dispersion liquid in which a plurality of bacteria are dispersed. The container has a bottom surface and an inner side surface. A thin film for converting the laser beam from the laser beam source into heat is formed on the bottom surface. At the inner side surface, immersion wetting occurs by the dispersion liquid when the inner side surface comes into contact with the dispersion liquid. The thin film is configured to produce a thermal convection in the dispersion liquid by heating the dispersion liquid. The inner side surface is configured to produce a Marangoni convection at a gas-liquid interface as an interface between the dispersion liquid and gas around the dispersion liquid.
