A system and method for automated single cell capture and processing is described, where the system includes a deck supporting and positioning a set of sample processing elements; a gantry for actuating tools for interactions with the set of sample processing elements supported by the deck; and a base supporting various processing subsystems and a control subsystems in communication with the processing subsystems. The system can automatically execute workflows associated with single cell processing, including mRNA capture, cDNA synthesis, protein-associated assays, and library preparation, for next generation sequencing.

A digital microfluidic device including an active matrix of propulsion electrodes controlled by thin-film-transistors. The device includes at least two areas of different propulsion electrode densities. One area may be driven by directly-driving the propulsion electrodes from a power supply or function generator. In the first, higher density region; a first dielectric layer covers the propulsion electrodes. The first dielectric layer has a first dielectric constant and a first thickness. In the second, lower density region, a second dielectric layer has a second dielectric constant and a second thickness covering the propulsion electrodes.

The present invention relates to a device (10) for use in fluid sample analysis. It is described to position (310) a top part (20) of the device (10) adjacent to a base part (30) of the device so as to define a fluidic receiving region in between, the top part being provided with a through opening fluidly connected to the fluidic receiving region, and the bottom part being provided with a radiation window adjacent to the fluidic receiving region. A fluidic sample is supplied (320) through the opening (24). The fluidic sample is moved laterally (330) in the fluid receiving region without the use of an intermediary membrane between the top part and the base part. A radiation is emitted (340) to the fluid receiving region. A radiation is detected (350) that is reflected by the device. A presence of the fluidic sample is determined (360) on the basis of a measured reflectance value based on the detected radiation.

A microfluidic device comprising a channel within a substrate and a condenser or a hydrodynamic focusing chamber along the channel, configured to focus a fluid containing particles of a plurality of sizes. A negative angle deterministic lateral displacement (DLD) array is configured to receive the focused fluid and separate the particles in the focused fluid into three sizes ranges. The negative angle DLD array comprises a plurality of rows of pillars, wherein the rows of pillars are positioned to repeat a pattern every N rows with a shift of M columns, N and M are relatively coprime, and N is greater than 1.

The present invention provides a novel method for the classification of adjuvants. In one embodiment, the present invention provides a method for generating organ transcriptome profiles for adjuvants, said method comprising: (A) a step for obtaining expression data by performing transcriptome analysis for at least one organ of a target organism by using at least two adjuvants; (B) a step for clustering the adjuvants with respect to the expression data; and (C) a step for generating the organ transcriptome profile for the adjuvants on the basis of the clustering.

A method for detecting biomarkers with shortened test time and maximized precision. A sample from the body fluid is made to flow over a sensor surface coated with a capture antibody to allow binding of a biomarker in the sample to the capture body. An optical method detects and counts the individual binding events along the sensor surface with single molecule resolution, and difference in the binding events along the sensor surface is detected in real time and analyzed to determine the biomarker concentration.

A device includes a first container having a floor and walls extending from the floor to an opening opposing the floor. The walls include opposing ledges at an interior of the first container. A second container has a first open end, sides, and a second end opposing the first open end. The second end has at least one hole adapted to receive a biopsy specimen cup. The first and second containers are made from opaque materials. A translucent panel has a notch in an edge thereof. The translucent panel is disposed on the ledges and spans the interior of the first container. The opening of the first container is sized to slidingly receive the second container wherein the first open end of the second container rests on the translucent panel. A light source is disposed in the first container between the translucent panel and the floor of the first container.

A microfluidic valve may include a first portion of a liquid conduit to contain a gas, a second portion of a liquid conduit to contain a liquid, and a constriction between the first portion and the second portion and across which a capillary meniscus is to form between the gas and the liquid. The microfluidic valve may further include a drop jetting device within the second portion to open the valve by breaking the capillary meniscus across the constriction.

A single junction sorter for a microfluidic particle sorter, the single-junction sorter comprising: an input channel, configured to receive a fluid containing particles; an output sort channel and an output waste channel, each connected to the input channel for receiving the fluid therefrom; a bubble generator, operable to selectively displace the fluid around a particle to be sorted and thereby to create a transient flow of the fluid in the input channel; and a vortex element, configured to cause a vortex in the transient flow in order to direct the particle to be sorted into the output sort channel.

An exemplary mobile impedance-based flow cytometer is developed for the diagnosis of sickle cell disease. The mobile cytometer may be controlled by a computer (e.g., smartphone) application. Calibration of the portable device may be performed using a component of known impedance value. With the developed portable flow cytometer, analysis may be performed on two sickle cell samples and a healthy cell sample. The acquired results may subsequently be analyzed to extract single-cell level impedance information as well as statistics of different cell conditions. Significant differences in cell impedance signals may be observed between sickle cells and normal cells, as well as between sickle cells under hypoxia and normoxia conditions.
