Abstract: Systems and associated methods and techniques for illuminating and imaging a device, such as a microfluidic or microarray device, are described herein. An optical source that illuminates the planar surface at an oblique angle can be used with optical components, such as an offset optical shaping rod and a wedge prism, used to provide uniform illumination across the planar surface and allow the illumination to appropriately reach the target illumination area despite the geometric limitations imposed by the presence and position of imaging, microfluidic control, and/or thermal cycling components.

Abstract: Methods for cell analysis are provided, comprising cell capturing, characterization, transport, and culture. In an exemplary method individual cells (and/or cellular units) are flowed into a microfluidic channel, the channel is partitioned into a plurality of contiguous segments, capturing at least one cell in at least one segment. A characteristic of one or more captured cells is determined and the cell(s) and combinations of cells are transported to specified cell holding chamber(s) based on the determined characteristic(s). Also provided are devices and systems for cell analysis.

Abstract: An analytical instrument has a sample introduction system for generating a stream of particles from a sample. An ionization system atomizes and ionizes particles in the stream as they are received. The instrument has an ion pretreatment system and a mass analyzer. The ion pretreatment system is adapted to transport ions generated by the ionization system to the mass analyzer. The mass analyzer is adapted measure the amount of at least one element in individual particles from the stream by performing mass analysis on the ions from the atomized particles. The instrument can be adapted to measure the amount of many different tags, for example at least five different tags, at the same time to facilitate multi-parametric analysis of cells and other particles.

Abstract: A thermal cycler for a microfluidic device includes a controller operable to provide a series of electrical signals, a heat sink, and a heating element in thermal communication with the heat sink and operable to receive the series of electrical signals from the controller. The thermal cycler also includes a thermal chuck in thermal communication with the heating element. The thermal chuck comprises a heating surface operable to make thermal contact with the microfluidic device. The heating surface is characterized by a temperature ramp rate between 2.5 degrees Celsius per second and 5.5 degrees Celsius per second and a temperature difference between a first portion of the heating surface supporting a first portion of the microfluidic device and a second portion of the heating surface supporting a second portion of the microfluidic device is less than 0.25° C.

Abstract: Methods, systems, and devices are described for multiple single-cell capturing and processing utilizing microfluidics. Tools and techniques are provided for capturing, partitioning, and/or manipulating individual cells from a larger population of cells along with generating genetic information and/or reactions related to each individual cell. Different capture configurations may be utilized to capture individual cells and then processing each individual cell in a multi-chamber reaction configuration. Some embodiments may provide for specific target amplification, whole genome amplification, whole transcriptome amplification, real-time PCR preparation, copy number variation, preamplification, mRNA sequencing, and/or haplotyping of the multiple individual cells that have been partitioned from the larger population of cells. Some embodiments may provide for other applications. Some embodiments may be configured for imaging the individual cells or associated reaction products as part of the processing. Reaction products may be harvested and/or further analyzed in some cases.
