MANIFOLDS, SYSTEMS AND METHODS FOR CONDUCTING BIOLOGICAL STUDIES UNDER FLOW
Some embodiments of the disclosure disclose manifolds, microfluidic systems and methods that provide control over fluid flow distribution to an array of bio-scaffolds contained within the manifolds. In some embodiments, multiple perfusates may be injected into the manifold via multiple inlets where the manifold contains a bio-assembly with a substrate having a bio-scaffold disposed thereon. Biological investigations of the perfusates may then be conducted in the vascular components and chambers of the bio-scaffold.
SYSTEMS, METHODS, AND APPARATUS FOR AUTOMATED SELF-CONTAINED BIOLOGICAL ANALYSIS
Systems, apparatus, and methods for conducting amplification-based analyses, including PCR testing. In one illustrative embodiment, a system may include a testing container assembly and a testing unit. The testing container assembly may include a sample collection port, a sample preparation chamber, and a reaction chamber. The sample collection port may include a bottom opening sealed by a plug member. In use, the testing container assembly may be placed in a seat of the testing unit with a sample in the sample collection port, closed by a lid. A plunger may dislodge the plug member and the sample drawn into the sample preparation chamber. Once sample preparation is complete, a channel may be opened, and the prepared sample flows into the reaction chamber which is then sealed. Testing including amplification reactions, may then be performed, followed by detection, as by detecting fluorescent emissions in the reaction chamber.
ANALYTE SENSING SYSTEM AND CARTRIDGE THEREOF
A sensing system is disclosed. The sensing system includes a sensor cartridge and a readout device. The sensor cartridge includes a sensing device and a micro-channel-structure. The sensing device includes a chip member and an electrode member arranged projectively offset from each other.
Method of performing droplet-based assays
Method of analysis. In the method, a first emulsion and a second emulsion substantially separated from one another by a spacer fluid may be formed. The first emulsion, the spacer fluid, and the second emulsion may be flowed in a channel from a fluid inlet to a fluid outlet of a heating and cooling station having two or more temperature-controlled zones, such that each emulsion is thermally cycled to promote amplification of a nucleic acid target in droplets of the emulsion. Amplification data may be collected from individual droplets of each emulsion downstream of the heating and cooling station. A level of the nucleic acid target present in each emulsion may be determined based on the amplification data collected from the individual droplets of the emulsion.
Unitary biochip providing sample-in to results-out processing and methods of manufacture
A biochip for the integration of all steps in a complex process from the insertion of a sample to the generation of a result, performed without operator intervention includes microfluidic and macrofluidic features that are acted on by instrument subsystems in a series of scripted processing steps. Methods for fabricating these complex biochips of high feature density by injection molding are also provided.
ALL-IN-ONE SELF TEST KIT
An all-in-one self test kit includes: a test tool having a reagent container adapted to store a diagnosis reagent therein and a diagnosis kit with a casing constituted of a first body and a second body and a diagnosis strip disposed inside the casing and having a sucking part for sucking the diagnosis reagent and a diagnosis part reacting to the diagnosis reagent sucked to the sucking part; a sub-body having a container insertion portion for inserting the reagent container thereinto and a kit insertion portion for inserting the diagnosis kit thereinto; a main body for inserting the sub-body thereinto; and a cap fastened and unfastened with an entrance of the main body to open and close the main body.
Method of Culturing and Analyzing at Least One Cell in a Microchamber Configured to Allow for Optical Inspection of the at Least One Cell, a Device for Use in the Method, a System and a Computer Program for Performing One or More of the Steps of the Method
The disclosure relates to a method of culturing and analyzing at least one cell in a microchamber configured to allow for optical inspection of the at least one cell, wherein liquid is extracted from the microchamber for analysis, characterized in that the analysis returns information about particles secreted from the at least one cell and that this information can be correlated to the individual cell and/or cell population. The disclosure further relates to a device for use in the method and a system and a computer program for performing one or more of the steps of the method.
RAPID TEST DEVICE HAVING MULTIPLE HETEROGENEOUS DIAGNOSTIC METHODS
An embodiment includes a sample receiving region, a first diagnostic element that includes one or more colorimetric analysis regions, and a second diagnostic element that includes one or more lateral flow assay analysis regions.

Microfluidic cartridge for processing and detecting nucleic acids
A system, configured to facilitate processing and detection of nucleic acids, the system comprising a process fluid container and a cartridge comprising: a top layer, a set of sample port-reagent port pairs, a shared fluid port, a vent region, a heating region, and a set of detection chambers; an intermediate substrate, coupled to the top layer comprising a waste chamber; an elastomeric layer, partially situated on the intermediate substrate; and a set of fluidic pathways, each formed by at least a portion of the top layer and a portion of the elastomeric layer, wherein each fluidic pathway is fluidically coupled to a sample port-reagent port pair, the shared fluid port, and a detection chamber, comprises a portion passing through the heating region, and is configured to be occluded upon deformation of the elastomeric layer, to transfer a waste fluid to the waste chamber, and to pass through the vent region.
MICROFLUIDIC CHIP WITH MIXED POROSITIES FOR RESERVOIR MODELING
Spherical grains and sacrificial particles are mixed in a suspension. The sacrificial particles are larger than the spherical grains. The suspension is injected into a channel in a microfluidic chip, and the spherical grains form microporous structures in the channel. The microporous structures are sintered in the channel. A solvent is injected into the channel, and the solvent dissolves the sacrificial particles and forms macropores between at least some of the microporous structures, thereby forming a mixed-porosity microfluidic chip.
