Apparatuses and methods are described for the use of optically driven bubble, convective and displacing fluidic flow to provide motive force in microfluidic devices. Alternative motive modalities are useful to selectively dislodge and displace micro-objects, including biological cells, from a variety of locations within the enclosure of a microfluidic device.

Microfluidic devices for optically-driven convection and displacement, kits and methods thereof

Methods, systems and kits are described herein for detecting the results of an assay. In particular, the methods, systems and devices of the present disclosure rely on a difference between the diffusion rates of a reporter molecule and an analyte of interest in order to quantify an amount of analyte in a microfluidic device. The analyte may be a secreted product of a biological micro-object.

Methods, systems and kits for in-pen assays

The present disclosure relates to an optical apparatus for imaging and/or manipulating micro-objects in a microfluidic device, such as a light-actuated microfluidic (LAMF) device, and related systems and methods. The optical apparatus can comprise a structured light modulator, a first and a second tube lens, an objective lens, a dichroic beam splitter, and an image sensor. The structured light modulator can be configured to receive unstructured light beams and transmit structured light beams for illuminating micro-objects located within an enclosure of the microfluidic device and/or selectively activating one or more of a plurality of dielectrophoresis (DEP) electrodes of the microfluidic device. The image light beams received by the image sensor can be used to form an image of at least a portion of the microfluidic device.

The second tube lens can be configured to transmit image light beams from the dichroic beam splitter to the image sensor. The image sensor can be configured to receive image light beams from the second tube lens. The image light beams received by the image sensor can be used to form an image of at least a portion of the microfluidic device.

Methods are provided to identify spatially and spectrally multiplexed probes in a biological environment. Such probes are identified by the ordering and color of fluorophores of the probes. The devices and methods provided facilitate determination of the locations and colors of such fluorophores, such that a probe can be identified. In some embodiments, probes are identified by applying light from a target environment to a spatial light modulator that can be used to control the direction and magnitude of chromatic dispersion of the detected light; multiple images of the target, corresponding to multiple different spatial light modulator settings, can be deconvolved and used to determine the colors and locations of fluorophores. In some embodiments, light from a region of the target can be simultaneously imaged spatially and spectrally. Correlations between the spatial and spectral images over time can be used to determine the color of fluorophores in the target.
