CENTRIFUGAL MICRO-FLUIDIC DISK FOR DETECTING THE PRESENCE AND CONCENTRATION OF AN ANALYTE OF INTEREST

The presently disclosed technology may utilize micro-fluidic disk technology, including integrated reagent and/or control one-time use fluid packs that improve functionality and ease of use of the presently disclosed disk. In various implementations, fluids within the disk may move radially inward as well as radially outward as required to functionally achieve the methods described herein. The presently disclosed technology may also be used to distinguish an analyte of interest from the background noise of one or more metabolites thereof in a fluid sample. This may be achieved by magnetically pre-separating some or all metabolites from the analyte of interest within the fluid sample. Using the disclosed techniques, detection of the analyte of interest is not obscured by other compounds leading to false positive test results.

Automatic container processing apparatus

According to one embodiment, an automatic container processing apparatus includes a tube socket, an operation part, and a control device. The tube socket has a container holding part for holding a container. The operation part is capable of operating the container holding part of the tube socket. The control device controls the operation part. The container held by the container holding part is dropped by operating the operation part.

Manipulation of microparticles in microfluidic systems

An array of transportable particle sets is used in a microfluidic device for performing chemical reactions in the microfluidic device. The microfluidic device comprises a main channel and intersecting side channels, the main channel and side channels forming a plurality of intersections. The array of particle sets is disposed in the main channel, and the side channels are coupled to reagents. As the particle sets are transported through the intersections of the main channel and the side channels, reagents are flowed through the side channels into contact with each array member (or selected array members), thereby providing a plurality of chemical reactions in the microfluidic system.

AUTOMATIC CELL ISOLATION AND COLLECTION SYSTEM

An automatic cell isolation and collection system for sorting out target cells from a sample includes a crush module, a centrifuge module, a transport module, and a control unit. The centrifuge module includes centrifuge tubes and a magnetic mechanism providing a magnetically attractive force to at least one of the centrifuge tubes. The control unit electrically communicates with the crush module, the centrifuge module, and the transport module, and controls operation of the crush module, transport of the sample via the transport module after the sample is crushed by the crush module, centrifugation of the centrifuge module, and operation of the magnetic mechanism for providing the magnetically attractive force.

Automated driving of an assay

The invention herein relates to conducting assays with an apparatus including a substantially transparent assay cartridge loaded with magnetic beads, and a magnet carrier base positioned below a scanning platform holding the assay cartridge. The assay cartridge includes magnetic beads, sample and control solutions in some wells, and assay reagents in others. A microcomputer controls a stepping motor which controls movement of the magnet carrier base, and causes the magnetic beads to travel from one well to another. An electromagnetic coil-spring assembly induces mixing of well contents with the magnetic beads on actuation. The assay cartridge is authenticated by sending its encoded identifier to a server or website, and assay instructions are provided remotely to the microcomputer. Following assay completion, the cartridge can have color change or other assay indication detected, and the results sent to the server or website or another recipient.
