  • Patent number: 9447407
    Abstract: The present invention generally relates to modified substrates such as membranes for use in bioartificial organs, such as bioartificial kidneys, and other applications. Certain aspects are generally directed to a membrane or other substrate modified to facilitate the attachment of cells. In one set of embodiments, the substrate or membrane may be at least partially coated with an adhesive such as 3,4-dihydroxy-L-phenylalanine (DOPA), poly(dopamine), or other adhesive comprising a molecule having a catechol moiety, for example on one side of the membrane or substrate. On at least a portion of the adhesive coated portion of the substrate, a protein may be coated, such as an extracellular matrix protein (for example, a collagen), to which cells such as primary human renal proximal tubule cells may be adhered. Surprisingly, such a dual coating may be used to promote the attachment of such cells to a membrane or other substrate that otherwise may not promote cell adhesion.

  • Publication number: 20160230213
    Abstract: A multiplexed polymerase chain reaction (PCR) DNA detection system and a method for DNA detection within the PCR system are provided. The PCR DNA detection system includes a color charge-coupled device (CCD) camera, fluorophore-quencher probes and an imaging chamber. The fluorophore-quencher probes are selected in response to fluorophores quenched by the fluorophore-quencher probes corresponding to three selected primary colors and peak channel responses of the CCD camera such that emission profiles of the fluorophores substantially match the three selected primary colors and peak emission profiles of the fluorophores correspond to the peak RGB channel responses of the CCD camera. A DNA sample and the fluorophore-quencher probes are located within the imaging chamber. The color CCD camera is focused on the imaging chamber for simultaneous detection of up to three targets from fluorescence of the DNA sample and the fluorophore-quencher probes.
