The invention provides a version of fluorescent in situ hybridization (FISH) in which all the steps are performed at physiological temperatures, i.e., body temperature, to detect and identify pathogenic bacteria in clinical samples. Methods of the invention use species-specific fluorescent probes to label clinically important infectious bacteria. A sample such as a urine sample is loaded into a cartridge, fluorescently labeled, and imaged with a microscope. Labelled bacteria are pulled down onto an imaging surface and a dye cushion is used to keep unbound probes off of the imaging surface. A microscopic image of the surface shows whether and in what quantities the infectious bacteria are present in the clinical sample.

Flow cell devices, cartridges, and systems are described that provide reduced manufacturing complexity, lowered consumable costs, and flexible system throughput for nucleic acid sequencing and other chemical or biological analysis applications. The flow cell device can include a capillary flow cell device or a microfluidic flow cell device.

A flow control system for a microfluidic device includes: a plurality of fluid flow controllers, each fluid flow controller associated with a respective microfluidic device inlet of the microfluidic device, and wherein each fluid flow controller includes: a controller inlet for receiving a fluid flow, a first fluid channel and a second fluid channel, each of the first and the second fluid channels having a first end connected to the controller inlet and a second end connected to a supply channel, and a valve for selecting the fluid flow to be passed from the controller inlet to the first fluid channel or to the second fluid channel, wherein the first fluid channel has a first flow resistance that smaller than a second flow resistance of the second fluid channel.

The present disclosure relates to a self-assembled peptide nanostructure including at least one amphiphilic peptide and a biosensor using the same. The amphiphilic peptide is a hairpin-shaped amphiphilic peptide including a hydrophilic domain having an α-helical structure and a hydrophobic domain. The N-terminal of the hydrophobic domain is a pyrene group. Since the self-assembled peptide nanostructure is derived from an RNA, DNA or amino acid sequence capable of recognizing a specific target substance, it does not recognize other substances but exhibits high selectivity for the target substance. Specifically, since the self-assembled peptide nanostructure has an excimer fluorescence peak at 480 nm through binding with the target substance, it can be usefully used in medical applications such as diagnosis of diseases.

A multiplex PCR chip capable of simultaneously detecting multiple target genes and a multiplex PCR method using the same are proposed. More specifically, in the multiplex PCR chip and multiplex PCR method, after a plurality of spatially separated particle-forming grooves is formed in one or more reaction chambers and a probe in a solution state is injected into the particle-forming grooves, planar shapes of the particle-forming grooves are varied or shapes and patterns of particle holders respectively formed on inner surfaces of the particle-forming grooves are varied, and the probe including primers specifically hybridizing with sequences of different nucleic acid molecules is injected into the particle-forming grooves, whereby simultaneous multiplex detection is possible by allowing multiple target genes to be detected on the basis of positions and shapes of the probe particles and the shapes and patterns of the particle holders respectively formed inside of the probe particles.

A biochip compatible with very small blood sample volumes is used for delecting for detecting hemoglobin disorders and monitoring disorders associated with aberrant blood cell deformability and adhesion, including disease severity, upcoming pain crisis, treatment response, and treatment effectiveness in a clinically meaningful way.

Cell monitoring apparatus includes sensing chip and channel module. Sensing chip includes channel region, source and drain regions, and sensing film. The channel region includes first semiconductor material. The source and drain regions are disposed at opposite sides of the channel region, and include a second semiconductor material. Sensing film is disposed on the channel region at a sensing surface of the sensing chip. Channel module is disposed on the sensing surface of sensing chip. A microfluidic channel is formed between the sensing surface of the sensing chip and a proximal surface of the channel module. The microfluidic channel includes a culture chamber and a micro-well. The culture chamber is concave into the proximal surface of the channel module, and overlies the channel region. The micro-well is concave into a side of the culture chamber, and directly faces the sensing film.

Provided is a rotatable microfluidic device for conducting simultaneously two or more assays. The device includes a platform which can be rotated, a first unit which is disposed at one portion of the platform and detects a target material from a sample using surface on which a capture probe selectively binds to the target material is attached, and a second unit which is disposed at another portion of the platform and detects a target material included in the sample by a different reaction from the reaction conducted in the first unit.

A microbial sample collection apparatus includes a double-sided attachment member having opposed attachment surfaces such as adhesive surfaces. A sampling member adheres to one of the opposed surfaces of the double-sided attachment member. A remaining surface of the double-sided attachment member is attachable to a face covering, i.e. face mask, of a test subject. A sample collector adheres the sampling member to a selected location on a face mask interior surface via the double-sided adhesive attachment therebetween. In this manner, microbial samples are cumulatively collected from the exhalation breath path of the test subject wearing the face mask.
