A portable point of care device (1) for use in testing a biological sample, the device comprising: a sample collection member (4), a test cartridge (2), and a reader (220).

An optofluidic diagnostic system and methods for rapid analyte detections. The system comprises an optofluidic sensor array, a test plate and an optical detection cartridge. The sensor array supports one or more distinct sensor units, each having a reactor section designed to temporarily enter a series of different kinds of wells in the test plate. One kind of well is a sample reservoir that holds reagent solution to be transferred into the reactor section. Another kind of well is a drainage chamber that removes reagent solution from the reactor section. A third kind of well is a colorant reservoir that holds a colorant reagent transferable into a reactor section. Finally, the sensor unit is transferred to the optical detection cartridge where it is placed into an isolation booth during the optical detection process so that its flat observation face is stationed in a viewing window opposite an optical detector lens.

The invention provides a multi-well plate reader for providing simultaneous transmission of stimulation light to, and detection of emission light from, individual wells of a multi-well plate at a plurality of distinct wavelengths.

The present disclosure provides a sensor substrate capable of detecting a trace amount of an analyte. This sensor substrate according to the present disclosure is a sensor substrate comprising a metal microstructure that generates surface plasmon when irradiated with excitation light. The metal microstructure is composed of a plurality of protrusions disposed in a planar shape. The plurality of the protrusions are disposed in such a manner that imaginary lines V each passing through a center between adjacent protrusions draw a honeycomb shape in a plan view. Each of the plurality of the protrusions has a substantially hexagonal shape in the plan view. A depth in a thickness direction of the sensor substrate of a gap present between the adjacent protrusions is larger than a radius of an imaginary circle inscribed in a hexagon forming the honeycomb shape.

A flow path device includes a first portion, and a second portion. The first portion includes a resin first body and a first reinforcement. In the first body, a first connector connects a first outer portion and a first joint having a groove pattern defining a first flow path.

The first reinforcement is between and bonded to the first outer portion and the first joint, and includes first protrusions protruding from the first body and including two specific-shaped portions. The second portion includes a resin second body and a second reinforcement. In the second body, a second connector connects a second outer portion and a second joint, and through-holes connect to the first flow path. The second reinforcement is between and bonded to the second outer portion and the second joint, and includes second protrusions protruding from the second body and including two specific-shaped portions.

Disclosed are cartridge components, cartridges, systems, and methods for isolating analytes from biological samples. In various aspects, the cartridge components, cartridges, systems, and methods may allow for a rapid procedure that requires a minimal amount of material from complex fluids.

A microfluidic device, a method of using a microfluidic device and a micro total analysis system are provided. The microfluidic device includes a first substrate, and the first substrate includes a base substrate and a pixel array. The pixel array includes a plurality of pixels and is on the base substrate, and each of the plurality of pixels includes a driving electrode. Driving electrodes of two adjacent pixels are in different layers.

Provided is a cell culture test device including a plurality of well units. Each of the well units includes a first inlet portion through which a first fluid is introduced, a first accommodation space communicating with the first inlet portion to accommodate a flow of the first fluid introduced through the first inlet portion, a second inlet portion through which a second fluid is introduced, and a second accommodation space in which the second fluid is accommodated. The second accommodation space accommodates an island structure connected with an island-connecting structure extending from the wall surface of the second accommodation space. A third inlet portion through which an antibiotic is loaded is formed above the island structure. The antibiotic loaded through the third inlet portion is fixedly accommodated on the inner and outer surfaces of the island structure.

The present invention relates to provide, among other things, the methods, devices, and systems that can simply and quickly collecting and analyzing a tiny amount of vapor condensates (e.g. exhaled breath condensate (EBC)).

A fluidic device (1) comprises a flow chamber (2) for accommodating a biological specimen on a carrier portion (3) and at least one flow channel (4a, 4b, 4c, 4d) fluidly connected to the flow chamber (2), the fluidic device (1) having a layered structure comprising a bottom plate (5), a cover plate (6) and an insert (7) in between, the insert (7) comprising the carrier portion (3) and a frame portion surrounding the carrier portion (3), and being elastomeric in order to be able to clamp a biological specimen between an incision in the carrier portion (3).
