    Abstract: The invention provides methods and devices for detecting the presence of one or more target analytes in a sample employing a channel having affixed therein one or more binding partners for each target analyte. Assays are carried out by transporting the sample through the channel to each successive binding partner so that target analyte present in said sample binds to the corresponding binding partner. The sample is then transported beyond the binding partner(s), followed by detection of any target analyte bound to each binding partner. In one embodiment, binding efficiency is increased by the use of segmented transport, wherein a first bolus or bubble of a fluid that is immiscible with the sample precedes the sample during transport and a second bolus or bubble of a fluid that is immiscible with the sample follows the sample. Many configurations are possible for the device of the invention.

    Abstract: Methods and apparatuses for selecting and arranging clinically relevant chromosomal loci allow an exemplary diagnostic array to simultaneously test for numerous genetic alterations that occur in many different parts of the human genome. Clinically irrelevant or ineffective loci are eliminated. One implementation increases reliability and accuracy by dividing the base-pair sequence of each chromosomal locus into segments and then assigning nucleic acid clones for comparative genomic hybridization to each different segment. The segments may overlap for increased resolution and control. Clones representing segments that are adjacent on a native chromosome are placed in non-adjacent target areas of the array to avoid interfering hybridization reactions. Arrangement motifs within an array may be redundantly repeated for high availability and increased reliability and accuracy of results. Techniques, hardware, software, logic engines, loci collections, and diagnostic arrays are described.

    Abstract: A substrate for biochips with which immobilization is easy, which does not exhibit self-fluorescence, which is easy to manufacture, and which is excellent in flatness and surface precision, is disclosed. A substrate having a substrate body of the biochip, which is made of a metal, and a carbon layer having functional groups formed on the metal substrate body is used as a substrate for biochips. Since the substrate body of the substrate for biochips is made of a metal, the substrate is not only easy to manufacture, but also free from cracking and chipping, so that it allows easy handling, and high flatness and surface precision can be attained. Therefore, the problem that the optical system is hard to focus when detecting fluorescence does not occur. Moreover, since the substrate body is made of a metal, it does not emit fluorescence by itself. In addition, since the carbon layer has functional groups such as amino groups, biologically relevant substances can be easily immobilized.

  • Publication number: 20100144556
    Abstract: An embodiment can be the use of motor proteins for cargo loading and transport in nano-devices and systems. One embodiment of the use of motor proteins can be adding biotin-binding proteins to a substrate by patterning, binding biotinylated F-actin to the biotin-binding proteins, aligning the bound F-actin in a preferred direction using a flow field, and using myosin coated particles to transport items attached to the particle throughout the substrate. Another embodiment of the use of motor proteins can be adding biotin-binding proteins to a substrate by patterning, adding a flow field, injecting F-actin so that the F-actin is bound and aligned simultaneously, and using myosin coated particles to transport items attached to the particle throughout the substrate. In either embodiment the F-actin can be capped with a biotinylated cap before binding to the biotin-binding proteins.
