Provided is a genome extraction device including a safety clip combined with an inner chamber, more particularly a genome extraction device to which the above-described dual chamber structure is applied so that the genome extraction device can be stored stably for a long time without the risk of reagent leakage and an inner chamber is moved up and down by way of vibration generated during a production and distribution process of a product so that a sealing member for sealing upper openings and lower openings of the inner chamber can be prevented from being perforated.

A microfluidic system includes a fluidic platform having a surface, a first liquid disposed onto the fluidic platform, and a droplet disposed onto the first liquid. The first liquid has a first temperature. The droplet has a second temperature higher than the first temperature so that the droplet is levitated above the first liquid by a cushion of vapor of the first liquid. In an embodiment, a device is configured to provide a magnetic field that has variable strength across the surface. A location of a magnetic droplet relative to the surface area is affected by the magnetic field. A method includes providing a fluidic platform, providing a magnetic field, introducing a first liquid onto the fluidic platform, introducing a first magnetic droplet onto the first liquid, and locally varying the magnetic field.

A method is provided for testing for presence of a particulate selected from the group consisting of: a microorganism, a fungus, a bacteria, a spore, a virus, a mite, a biological cell, a biological antigen, a protein, a protein antigen, and a carbohydrate antigen. The method includes (a) collecting, in a tube (22), fluid that potentially contains the particulate, (b) using a plunger (24) to push the fluid through a filter (26) disposed at a distal portion of the tube or at a distal end of the plunger, and subsequently, (c) while the filter is inside the tube, ascertaining if any of the particulate was trapped by the filter by applying a particulate-presence-testing-facilitation solution to the filter. Other embodiments are also described.

Disclosed herein is a system to detect and characterize individual particles and cells using at least either optic or electric detection as the particle or cell flows through a microfluidic channel. The system also provides for sorting particles and cells or isolating individual particles and cells.

The present application is directed to the processing of a biological sample into its constituent components for use in ART and includes introducing a sample into a first volume disposed adjacent a second volume including buffer solution, wherein the first and second volumes are adapted for fluid communication therebetween, selectively separating the first volume from the second volume with a movable closure member disposed therebetween, wherein the step of selectively separating the first volume from the second volume includes moving the closure member so that a fluid communication aperture is formed by one or a combination of the closure member or the closure member in combination with the first and second volumes to allow fluid communication between the first volume and the second volume such that motile cells migrate from the sample in the first volume to the buffer solution in the second volume.

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.

Provided herein is a method of concentrating a tethering complex in a region of an amphiphilic layer, such as a lipid membrane. Also provided herein are methods of assembling a tethering complex; methods of concentrating an analyte in the region of a detector; amphiphilic layers; and arrays and devices for use in the disclosed methods.

Aspects of the present disclosure include sample preparation cartridges including a cylindrical structure and one or more covers. The cylindrical structure further includes a top, a bottom, an annular wall, a plurality of cavities in the annular wall that form a plurality of open-sided chambers on the annular wall and one or more interconnections providing fluidic communication between the plurality of chambers. The one or more covers cover the open side of the plurality of chambers. Also provided is a cylinder housing comprising one or more magnets. The sample preparation cartridge is removably disposed into the cylinder housing or adjacent to the cylinder housing. Methods of using the sample preparation device are also provided.

Sample cartridge, valve assembly and processing methods for providing mechanical lysis, chemical lysis or both for a given fluid sample are provided herein. Such systems can include a sample processing cartridge having a valve assembly configured for transport of the processing of fluid sample within the sample cartridge. The valve assembly can include a valve body and cap that secure a filter therebetween and facilitate inflow of mechanical or chemical lysing agents as needed for a fluid sample. Assay workflows for performing both mechanical and chemical lysis of a fluid sample within the same workflow of a single universal sample cartridge are also provided.

An apparatus for gene amplification includes a gene amplification chip including a well configured to accept a sample that is loaded into the well; the gene amplification chip being configured to: thermally dissolve the sample in the well so that a microbe present in the sample is thermally dissolved in the well to release genes in the microbe; and amplify the released genes in the well. The apparatus for gene amplification also includes a temperature controller configured to control a thermal dissolution temperature and a gene amplification temperature of the well.
