OPTICAL DISTORTION CORRECTION FOR IMAGED SAMPLES
Techniques are described for dynamically correcting image distortion during imaging of a patterned sample having repeating spots. Different sets of image distortion correction coefficients may be calculated for different regions of a sample during a first imaging cycle of a multicycle imaging run and subsequently applied in real time to image data generated during subsequent cycles. In one implementation, image distortion correction coefficients may be calculated for an image of a patterned sample having repeated spots by: estimating an affine transform of the image; sharpening the image; and iteratively searching for an optimal set of distortion correction coefficients for the sharpened image, where iteratively searching for the optimal set of distortion correction coefficients for the sharpened image includes calculating a mean chastity for spot locations in the image, and where the estimated affine transform is applied during each iteration of the search.
Multi-Well Plates for Creation of High-Density Arrays of Compartmentalized Cell Cultures for Usage in High Capacity Applications
The disclosure relates to multi-well plates having fluidic connections between neighboring wells that are useful to produce a cell culture substrate and compliant with American National Standards Institute of the Society for Laboratory Automation and Screening (ANSI/SLAS) microplate standards
FLOW CELL WITH ENHANCED WELL IMAGING RESOLUTION
Resolution of images used in processes such as sequencing by synthesis may be increased by structuring sites that would emit signals in the images to have different elevations. Differences in focus caused by these differences in elevation may be used to filter out background illumination, thereby providing an image in which in focus sites may be resolved even though the separation between any site and its nearest neighbor may be below the diffraction limit of the light that would be emitted.
Cell capture system and method of use
A cell capture system including an array, an inlet manifold, and an outlet manifold. The array includes a plurality of parallel pores, each pore including a chamber and a pore channel, an inlet channel fluidly connected to the chambers of the pores; an outlet channel fluidly connected to the pore channels of the pores. The inlet manifold is fluidly connected to the inlet channel, and the outlet channel is fluidly connected to the outlet channel. A cell removal tool is also disclosed, wherein the cell removal tool is configured to remove a captured cell from a pore chamber.
Microfluidic devices with bubble diversion
A microfluidics device has one or more bubble diversion regions. Problems associated with the generation of air bubbles are avoided in a microfluidics device such as a cartridge, for use with a point of care (POC) diagnostics device, the cartridge being able to carry out downstream processing such as polymerase chain reaction (PCR) and/or nucleic acid capture. The bubble diversion region has a lower flow resistance than the flow resistance of an area of interest.

Microfluidic Mixer
A microfluidic mixer, formed by two parts, a first part being a substrate having formations defining fluid channels on an outer surface that is directed towards a second part, which is a flexible layer. The flexile layer has formations defining a fluid channel which, when the flexible layer is positioned over the substrate so as to cover the fluid channels of the substrate provides a fluid communication path. A section of said communication path comprises at least first and second fluid channels for providing first and second fluids. The first and second fluid channels merge before an inlet of a mixing chamber. The mixing chamber comprises perturbation formations. An outlet of the mixing chamber is connected to an outlet fluid channel. The flexible layer comprises points for compression at the inlet and outlet of the mixing chamber for closing the merged fluid channel. The perturbation formations of the mixing chamber are vertically arranged vertically with respect to an inner surface.
