Abstract: A feature value calculation device is a feature value calculation device that calculates a feature value indicating optical characteristics of an object to be measured in a flow cytometry method, the device including: a signal information acquisition unit to acquire signal information indicating a temporal change in intensity of the electromagnetic waves which is generated by a light detector receiving the modulated electromagnetic waves from the object to be measured; a region setting unit that sets a region to be processed in waveform data in which a feature value is calculated in a domain of the waveform data based on the signal information acquired by the signal information acquisition unit; and a feature value calculation unit that calculates the feature value from the waveform data in the region set by the region setting unit.

Abstract: The present disclosure provides methods and systems for ghost cytometry (GC), which may be used to produce an image of an object without using a spatially resolving detector. This may be used to perform image-free ultrafast fluorescence “imaging” cytometry, based on, for example, a single pixel detector. Spatial information obtained from the motion of cells relative to a patterned optical structure may be compressively converted into signals that arrive sequentially at a single pixel detector. Combinatorial use of the temporal waveform with the intensity distribution of the random or pseudo-random pattern may permit computational reconstruction of cell morphology. Machine learning methods may be applied directly to the compressed waveforms without image reconstruction to enable efficient image-free morphology-based cytometry.

Abstract: The present disclosure provides systems, devices, and methods for flow focusing in a microfluidic device. Flow focusing may be used in detection of objects, for example cells, in a stream of fluid passing through a fluidic device. The systems and devices may comprise a flow channel positioned between two sheath channels configured to direct fluid across the flow channel. Flow focusing microfluidic systems and devices disclosed herein may be robust to alignment errors. Systems and devices of the present disclosure may reduce the displacement of flow from the intended locations due to alignment errors. Also disclosed herein are methods for using such microfluidic systems and devices.

Abstract: The present disclosure provides a method for screening cells, the method including a step of preparing a plurality of cells which are tagged with a first barcode nucleic acid associated with a test target and treated with the test target, a step of sorting the plurality of cells based on cellular phenotype using an imaging cell sorter, and a step of identifying the test target used to treat each cell using the first barcode nucleic acid as an indicator.

Abstract: An imaging flow cytometer includes at least one flow channel through which an observation target flows, a light source which irradiates the flow channel with sheet-like excitation light, an imaging unit which images a specific cross-section of the observation target by imaging fluorescence from the observation target having passed through a position irradiated with the excitation light, and a three-dimensional image generation unit which generates a three-dimensional image of the observation target as a captured image on the basis of a plurality of captured images obtained by cross-sectional imaging by the imaging unit.

Abstract: A cell evaluation system includes physical measurement unit, a database, and evaluation unit. The evaluation unit refers to a relevance stored in the database, searches reference measurement information based on measurement information of a cell newly measured via the physical measurement unit, and evaluates the cell with biological measurement information associated with the searched reference measurement information.
