A system and method for ejecting one or more fluids from a digital dispense device. The method includes a) inputting to a memory a volume per unit area for each of the one or more fluids to be ejected from the digital dispense device; b) matching the volume per unit area to a device resolution for the digital dispense device; c) formatting fluid ejectors for the digital dispense device for the device resolution; and d) ejecting fluid from the digital dispense device to provide the volume per area for each of the one or more fluids.

Systems and methods for coverslipping a sample on a slide employ a coverslip tape. The systems and methods can reduce or eliminate the use of xylene and other toxic solvents for coverslipping.

An apparatus for providing an object to be medically examined by blowing is provided where air is blown into a container in which an object to be medically examined is stored, so as to make the uniform distribution state of the object to be medically examined from the inside of the container, thereby ensuring the sameness of the object to be medically examined, which is to be extracted from the container.

Devices and methods for the deposition of reagents onto cells or tissue samples are disclosed. Also disclosed are reagent compositions suitable for dispensing via a droplet-on-demand system.

The present invention is a specimen preparation method of preparing an observation specimen by placing an observation object on a light transmitting plate, comprising a conveyance step of conveying the observation object by a conveyance mechanism including a placement portion configured to place the observation object, and a transfer step of transferring the observation object from the placement portion of the conveyance mechanism onto the plate at a conveyance terminal end of the conveyance mechanism, wherein in the transfer step, a liquid is supplied to the placement portion on which the observation object is placed, and the observation object is carried by a flow of the liquid and transferred onto the plate.

A colorimetric sensor array includes a CMOS image sensor having a surface including pixels and a multiplicity of colorimetric sensing elements. Each sensing element has a sensing material disposed directly on one or more of the pixels. The colorimetric sensing elements are distributed randomly on the surface of the CMOS image sensor. Fabricating the colorimetric sensor array includes spraying a sensing fluid in the form of droplets directly on a surface of a CMOS image sensor and removing the solvent from the droplets to yield a multiplicity of sensing elements on the surface of the CMOS image sensor. Each droplet covers one or more pixels of the CMOS image sensor with the sensing fluid. The sensing fluid includes a solvent and a sensing material. The droplets are distributed randomly on the surface of the CMOS image sensor.

Systems and methods that enable automated spray deposition of biological specimens carried on microscope slides are described herein. Aspects of the technology are directed, for example, to automated specimen deposition systems and methods of generating high-quality, reproducible specimen-bearing microscope slides in automated processing systems.

Various examples of systems and methods are provided for slide processing. In one example, among others, a system for processing microscope slides includes a slide positioner that can adjust a position of a slide and a slide treatment system that can dispense a micro stream of a fluid at a location on the slide when the slide is positioned beneath a jet nozzle of the slide treatment system. The system can include a slide sled that can align a smearing slide with a surface of the slide including a fluid sample is disposed, and support the smearing slide at a predefined angle with respect to the surface of the slide. In another example, a method includes obtaining a slide including a sample disposed on a surface, positioning the slide below to a jet nozzle, and dispensing a micro stream of a fluid onto the sample using the jet nozzle.

Disclosed is plate or film for collecting and analyzing a sample. The plate or film includes a surface and a plurality of slices from the sample immobilized on the surface. Further, the plurality of slices are cut from the sample with equal thickness, and the plurality of slices are placed on the surface of the plate or film following their cutting order.

Provided is a sample pretreatment device configured to apply, to the surface of a sample, a solution in which a predetermined substance is dissolved or dispersed. In order to properly and efficiently unclog a nozzle due to the deposition of the crystal of a matrix substance, the device includes a spray unit (3) including a solution tube (32) for the solution to pass through, a gas tube (33) for a spray gas to pass through, and a nozzle part (30) configured to spray the solution arriving at the terminal end of the solution tube by ejection of the spray gas through the gas tube, as well as a cleaning liquid supplier (4, 41) configured to put a cleaning liquid on an opening of the nozzle part from outside the spray unit.
