A microfluidic device includes a first substrate including at least one microfluidic channel and a plurality of microwells, as well as a cooperating second substrate defining multiple split-walled cell trap structures that are registered with and disposed within the plurality of microwells. A method for performing an assay includes flowing cells and a first aqueous medium into a plurality of microwells of a microfluidic device, wherein each microwell includes a cell trap structure configured to trap at least one cell. The method further comprises flowing a nonpolar fluid with low permeability for analytes of interest through a microfluidic channel to flush a portion of the first aqueous medium from the microfluidic channel while retaining another portion of the first aqueous medium and at least one cell within each microwell. Surface tension at a non-polar/polar medium interface prevents molecule exchange between interior and exterior portions of microwells.

Device and method for high-throughput multiparameter measurements in one or more live and fixed cells

Systems and methods of using the same for functional fluorescence imaging of live cells in suspension with isotropic three dimensional (3D) diffraction-limited spatial resolution are disclosed. The method-live cell computed tomography (LCCT)-involves the acquisition of a series of two dimensional (2D) pseudo-projection images from different perspectives of the cell that rotates around an axis that is perpendicular to the optical axis of the imaging system. The volumetric image of the cell is then tomographically reconstructed.

An integrated technological platform enabling real-time quantitative multiparameter metabolic profiling, utilizing either or both of extra and intracellular optical sensors, individually or simultaneously. A scalable embedded micropocket array structure, generally fabricated on fused silica substrates, facilitates the integration of multiple, spatially separated extracellular sensors for multiparameter analysis in a container formed with the use of an activation mechanism forming part of a device configured to hold the container during the measurements. The creation of hermetically sealed microchambers is carried out with a pneumatically and/or mechanically and/or electromechanically driven device that is 'floating' within the holding device and that is optionally equipped with a vacuum/suction mechanism to hold a component of the container at its surface.

Integrated platform for characterization of single cells or small cell clusters

A microfluidic device useable for performing live cell computed tomography imaging is fabricated with a cover portion including a first wafer with at least one metal patterned thereon, a base portion including a second wafer with at least one metal patterned thereon and negative photoresist defining recesses therein, and a diffusive bonding layer including a negative photoresist arranged to join the cover portion and the base portion. A composition useful in live cell computer topography includes a long-chain polysaccharide at a concentration of from about 0.01% to about 10.0% in cell culture medium for supporting cell life while enabling cell rotation rate to be slowed to a speed commensurate with low light level imaging.

Microfluidic electrocage device and cell medium for trapping and rotating cells for live-cell computed tomography (CT)

Microfluidic devices for 3D hydrodynamic microvortical rotation of at least one live single cell or cell cluster, systems incorporating the devices, and methods of fabricating and using the devices and systems, are provided. A microfluidic chip rotates at least one live single cell or cell cluster in a microvortex about a stable rotation axis perpendicular to an optical axis within a chamber having a trapezoidal cross-sectional shape located below a flow channel. An optical trap may be used to position the cell or cells with the microvortex, and the cell or cells may be subject to live-cell or cell cluster computer tomography imaging.
