Having Biological Material Component Patents (Class 977/702)
  • Patent number: 7655269
    Abstract: The invention provides sensor, preferably biosensor devices and method of fabrication. The devices have significant advantages over the prior art methods having compatibility with future trends in clinical diagnostics and chemical detection. The underlying principle involves the integration of nanometer diameter, micron long metal or semiconductor rods onto a substrate to form a suspended nanomechanical cantilevers. The cantilever rods are rigidly attached to the substrate on one or both ends, and resonate at a characteristic frequency depending on the diameter, length, and stiffness of the rod. The metal or semiconductor rods are integrated onto the substrate using electrofluidic or fluidic assembly techniques. A receptor coating is placed on the metal or semiconductor rods prior to or following rod alignment using self-assembly chemistries.

  • Patent number: 7611906
    Abstract: Carbon nanotubes are grown on a first substrate. The CNTs grown on the first substrate are immersed in a biological solution at a predetermined depth to functionalize ends of the CNTs with a biological molecule. The functionalized CNTs are harvested from the first substrate. A second substrate is functionalized with a complementary biological modification, which is a complementary binding partner to the biological molecule functionalized to the ends of the CNTs. The functionalized CNTs are attached to the second substrate by way of the complementary binding partner.

  • Patent number: 7611579
    Abstract: A system for synthesizing nanostructures using chemical vapor deposition (CVD) is provided. The system includes a housing, a porous substrate within the housing, and on a downstream surface of the substrate, a plurality of catalyst particles from which nanostructures can be synthesized upon interaction with a reaction gas moving through the porous substrate. Electrodes may be provided to generate an electric field to support the nanostructures during growth. A method for synthesizing extended length nanostructures is also provided. The nanostructures are useful as heat conductors, heat sinks, windings for electric motors, solenoid, transformers, for making fabric, protective armor, as well as other applications.

  • Patent number: 7476786
    Abstract: The methods, apparatus and compositions disclosed herein concern the detection, identification and/or sequencing of biomolecules, such as nucleic acids or proteins. In certain embodiments of the invention, coded probes comprising a probe molecule attached to one or more nano-barcodes may be allowed to bind to one or more target molecules. After binding and separation from unbound coded probes, the bound coded probes may be aligned on a surface and analyzed by scanning probe microscopy. The nano-barcodes may be any molecule or complex that is distinguishable by scanning probe microscopy (SPM), such as carbon nanotubes, fullerenes, submicrometer metallic barcodes, nanoparticles or quantum dots. Where the probes are oligonucleotides, adjacent coded probes hybridized to a target nucleic acid may be ligated together before alignment and scanning probe microscopy (SPM) analysis. Compositions comprising coded probes are also disclosed herein.
