  • Patent number: 9097710
    Abstract: Apparatus for determining the quantity of a target protein, biomarker or analyte present in a sample, comprising a top plate and a bottom plate, each comprising a plurality of recesses arranged to form a plurality of rows extending parallel to one another, and a plurality of channels extending perpendicularly to the plurality of rows of the bottom plate; wherein the top plate and the bottom plate are assembled together so that the top plate is on top of the bottom plate and the recesses of the top plate communicate with the recesses of the bottom plate so as to form a plurality of rows; and wherein at least one of the top and bottom plate is configured to slide relative to the other of the top and bottom plate in order to form a plurality of columns, with each of the columns in communication with each of the channels.

  • Publication number: 20120164396
    Abstract: Provided is a direct write patterning method utilizing a mixture comprising an ink of choice and an ink carrier matrix. The method involves disposing the mixture on a tip or stamp and transporting the mixture from the tip or stamp on a surface to form a pattern that contains the ink. The method does not require chemical or physical modification of either the tip or stamp or the surface prior to transporting the mixture to the surface. The method can be applied for patterning hard inks such as nanomaterials and crystallized polymers and soft inks such as biomaterials including peptides and proteins. Also provided are related biomaterial and hard ink arrays.

  • Publication number: 20120006674
    Abstract: Disclosed herein is energy transfer on multisegmented nanowires via surface plasmon resonance excitation of visible light, such as solar energy, absorbed by metals sensitive to visible light and transferred to metals insensitive to visible light. The nanowires are prepared with controllable gap sizes between different segments by on-wire lithography (OWL).

  • Publication number: 20090155587
    Abstract: Multicomponent nanorods having segments with differing electronic and/or chemical properties are disclosed. The nanorods can be tailored with high precision to create controlled gaps within the nanorods or to produce diodes or resistors, based upon the identities of the components making up the segments of the nanorods. Macrostructural composites of these nanorods also are disclosed.
