  • Patent number: 9023640
    Abstract: A portable system for real time detection of the presence of an infectious agent in a biological sample employs a reagent which detects the presence of a specific infectious agent in the sample, and emits a detectable signal when the reagent reacts with the sample and detects the presence of the infectious agent. A test cartridge has a reaction chamber for receiving the sample and the reagent. The reaction chamber has a predetermined internal geometry and at least one inner surface. Introducing the sample and the reagent into the test cartridge mixes the sample and the reagent. A testing unit receives the test cartridge, and includes a sensor for detecting an emitted detectable signal.

  • Publication number: 20150004620
    Abstract: A method of identifying inhibitors of epithelial-mesenchymal transition (EMT). The method may comprise comparing different sets of image data obtained from one or more cell colonies before (T1) and after (T2) exposure to a possible inhibitor of epithelial-mesenchymal transition. The method may further comprise measuring the cell number and a spreading coefficient value in the one or more cell colonies for determining cell count ratio (CCR) and normalized cell dispersion ratio (CDR) for the one or more colonies. The possible inhibitor may then be identified to be an inhibitor of EMT if the determined CCR and CDR indicates that the possible inhibitor i) does not or marginally inhibit growth and inhibits EMT, or ii) inhibits growth and inhibits cell dispersion and optionally inhibits also EMT, or iii) is cytotoxic and inhibits cell dispersion and optionally inhibits also EMT.

    Abstract: A testing device uses a selectively deformable substrate to capture and retain spherical beads for genetic experimentation. A method of fabricating the device is described in which a silicon substrate can be coated with a photosensitive, bio-compatible polymer for photolithographic patterning using a single mask exposure. The polymer is patterned with a matrix of wells, each well capable of expansion to accept placement of a bead in the well, and contraction to secure the bead in the well. The polymer can exhibit piezoelectric properties that cause it to respond mechanically to a selected electrical excitation.
