Abstract:
A microfluidic device may include a sample distribution network including a plurality of sample chambers configured to be loaded with biological sample for biological testing of the biological sample while in the sample chambers. The sample distribution network may further include a plurality of inlet channels, each inlet channel being in flow communication with and configured to flow biological sample to a respective sample chamber, and a plurality of outlet channels, each outlet channel being in flow communication and configured to flow biological sample from a respective sample chamber. At least some of the sample chambers may include a physical modification configured to control the movement of the meniscus so as to control bubble formation or dried reagent positioned within the at least some sample chambers proximate the inlet channels in flow communication with the at least some sample chambers.

Abstract:
The present invention relates to a surface-clinging type robot that has reduced weight and better mobility by employing the lowest number of adhering plates and that allows three-dimensional movement between a wall and a ceiling as well as typical two-dimensional movement. The robot has two adhering plates. The second adhering plate moves upward by a first up/down driving unit while the first adhering plate is in contact with a surface, and rotates on the first adhering plate by a first horizontal rotating unit. Then the second adhering plate moves downward by the first up/down driving unit, and clings to the surface by a clinging force supplied thereto.
Abstract:
An assay card and devices and methods for isolating chambers on the assay card are described. The assay card comprises a substrate formed of one or more materials, e.g., plastic, having a softening temperature, the substrate defining channels communicating with respective reaction chambers. The assay card may be heated in a region of the channels to at least the softening temperature. The softened plastic may be deformed, e.g., with a tool which may or may not also provide the heat for softening the substrate. In this manner, the plastic of the substrate may be caused to at least partially obstruct the channels, thereby isolating the reaction chambers. The invention also relates to a method of manufacturing a tool device that includes pins for heating and deforming an assay card.
Abstract:
Systems and methods for multiple analyte detection include a system for distribution of a biological sample that includes a substrate, wherein the substrate includes a plurality of sample chambers, a sample introduction channel for each sample chamber, and a venting channel for each sample chamber. The system may further include a preloaded reagent contained in each sample chamber and configured for nucleic acid analysis of a biological sample that enters the substrate and a sealing instrument configured to be placed in contact with the substrate to seal each sample chamber so as to substantially prevent sample contained in each sample chamber from flowing out of each sample chamber. The substrate can be constructed of detection-compatible and assay-compatible materials.
Abstract:
The present invention relates to a photodetecting device protected from contamination by organic materials secreted from a living matter in the case that a photodetector is used for investigating characteristics of the living matter, and which easily blocks the influence of an external magnetic field. The photodetecting device includes a protection window formed in the front side facing a measured object, and a magnetic shielding tube providing a space for installing components of the photodetecting device such as a variable shutter, movable lens, protection window, and incidence window. Additionally, the photodetecting device according to the present invention includes a drive means enabling remote control of photodetector movement, and provides an advantage that a tester may measure various points of a specimen more easily.
Abstract:
Apparatus and Methods are provided for a microfabricated fluorescence activated cell sorter based on an optical switch for rapid, active control of cell routing through a microfluidic channel network. This sorter enables low-stress, highly efficient sorting of populations of small numbers of cells (i.e., 1000 - 100,000 cells). The invention includes packaging of the microfluidic channel network in a self-contained plastic cartridge that enables microfluidic channel network to macro-scale instrument interconnect, in a sterile, disposable format.
Abstract:
A system and method are provided for large volume sample amplification adaptable for use with conventional PCR-based reactions as well as emulsion-based PCR reactions. A sample is retained in a pouch or flexible bag which permits bulk PCR amplification with efficient heat-transfer properties. For applications involving emulsion-based PCR amplification, the system and method provide improved uniformity in emulsion amplification and can be used to amplify large or small volume emulsions rapidly and reproducibly.
