A test container includes an inlet, a first storage portion, a second storage portion, a first flow channel that connects the first storage portion to the second storage portion, a first cylinder of which one end is connected to the first storage portion via a second flow channel and the other end is open to an outside, a second cylinder of which one end is connected to the second storage portion via a third flow channel and the other end is open to an outside, a first plug provided in the first cylinder, and a second plug provided in the second cylinder. An internal space including the first storage portion, the second storage portion, the first flow channel, the second flow channel, and the third flow channel is capable of being pressurized in a case where the first plug and the second plug are pressed and moved from the outside.

A mesoscale fluidic system comprises a substrate having a sample chamber and an analysis chamber. The sample chamber comprises a cell permeable filter defining a sample application compartment and a conditioning medium compartment. The sample chamber has a sample inlet port in the sample application compartment. The analysis chamber has an entry port and an exit port. The conditioning medium compartment is in fluid communication with the entry port of the analysis chamber via a channel. The sample application compartment is below the cell permeable filter and the conditioning medium compartment is above the cell permeable filter. The mesoscale fluidic system is suited for analysing cellular motility in a sample. Also disclosed is a method of estimating the quantity of motile cells in a sample and a method of extracting motile cells from non-motile cells.

The present invention provides point-of-need diagnostic devices and kits for detecting a target nucleic acid sequence in a sample. Methods of using the point-of-need diagnostic devices or the kits disclosed are also provided.

A point-of-care diagnostic system that includes a cartridge and a reader. The cartridge can contain a patient sample, such as a blood sample. The cartridge is inserted into the reader and the patient sample is analyzed. The reader contains various analysis systems, such as an electrophoresis detection system that uses electrophoresis testing to identify and quantify various components of the blood sample. The reader can process data from the various patient sample analysis to provide interpretative results indicative of a disorder, condition, disease and/or infection of the patient.

Provided are a gene detection kit and a gene detection device. The gene detection kit includes a kit body, a piston cylinder, and a piston. The kit body has an accommodating cavity and a plurality of reagent cavities. The piston cylinder is provided in the accommodating cavity, and the piston cylinder has a piston cavity. The piston is movably provided in the piston cavity along an axial direction of the piston cylinder. A first channel in communication with the piston cavity is provided on an outer circumferential surface of the piston cylinder, a plurality of second channels are provided on an inner wall of the accommodating cavity, each of the second channels is in corresponding communication with one of the reagent cavities, and the piston cylinder can move relative to the kit body, so that the plurality of second channels are alternately in communication with the first channel.

A closed system centrifuge tube is described and discussed herein that enables removal of waste and transfer and removal of samples via one or more ports of the centrifuge tube within the closed system, without exposing the sample to the outer environment. This may enable greater sample retention during sample processing and centrifugation of the sample.

The present invention provides devices and methods for generating a pulsatile fluid flow in a microchannel by means of external actuation of a thin flexible film. With the devices described herein, cycles of positive and negative actuation can be used to infuse or withdrawal fluid in a microchannel. Fluid can be recirculated over one or more microfluidic feature, such as a chemical or molecular receptor, biosensor, electrode, cell or biological material, chromatography feature, mixer, etc., in a way that would represent an advantage over the single-pass flow techniques common to most microfluidic devices. The devices and methods are particularly useful in vitro diagnostics (IVD), analytical chemistry, chromatography, and mixing applications in a variety of fields.

A lysis device including a sample vessel, at least one piezo element, and a controller is disclosed. The sample vessel has a microchannel formed therein. The sample vessel has at least one port extending through a surface to the microchannel. The piezo element is attached to the surface of the sample vessel. The controller has logic to cause the controller to emit a first signal including a series of frequencies to the at least one piezo element to cause the at least one piezo element to generate ultrasonic acoustic standing waves in the sample vessel, to receive a second signal indicative of measured vibration signals from the sample vessel detected by the at least one piezo element, and to determine a resonant frequency of the sample vessel using the measured vibration signals.

Systems, methods, and apparatuses are provided for self-contained nucleic acid preparation, amplification, and analysis.

A platform and method for conducting multi-variable combinational interactions are provided. An array of multiplexing chambers in formed in a body. The body also includes a common well communicating with each multiplexing chamber of the array of multiplexing chambers and a plurality of variable wells. Each of variable wells communicates with at least one multiplexing chamber of the array of multiplexing chambers. The common well is loaded with a first variable and different variables are loaded in each of the plurality of variable wells. The interaction of the first variable with at least one of the different variables in each multiplexing chamber of the array of multiplexing chambers is observed.
