First Claim
1. A microfluidic device for multiple single-cell capturing and processing, the microfluidic device comprising:
- a) a plurality of capture configurations coupled in series, wherein each respective capture configuration is configured to capture a single cell,(i) wherein each capture configuration comprisesa single input channel,a single output channel,a capture nest comprising one or more physical barriers configured to capture a single cell,a drain channel, anda pair of bypass channels, and(ii) wherein in each capture configurationthe capture nest is in fluidic communication with the drain channel,the capture nest is situated near a junction of the input channel and the pair of bypass channels,the drain channel is in fluidic communication with the input channel and the output channel such that solution that flows from the input channel through the drain channel exits the capture configuration through the output channel without flowing through the bypass channels,the bypass channels are in fluidic communication with the input channel and the output channel such that solution that flows from the input channel through the bypass channels exits the capture configuration through the output channel,the capture nest is configured to capture a single cell from a plurality of cells flowing through the input channel, andthe output channel is configured to allow cells to pass through said output channel to the next capture configuration in the series,wherein the only fluidic paths through which solution can flow into or out of the capture nest, drain and bypass channel portions of the capture configuration-comprises flow through the single input channel or a the single output channel; and
(b) a plurality of multi-chamber reaction configurations,wherein each respective multi-chamber reaction configuration is in fluidic communication with an output channel or input channel of a respective capture configuration from the plurality of capture configurations and said multi-chamber reaction configurations are configured for single-cell processing.

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.
