  • Functionalized surfaces and methods related thereto
    Patent number: 9759842
    Abstract: The disclosed subject matter provides a nanoaperture having a bottom surface and a side wall comprising gold. A surface of the side wall is passivated with a first functional molecule comprising polyethylene glycol. The bottom surface of the nanoaperture can be functionalized with at least one second molecule comprising polyethylene glycol, for example, a silane-PEG molecule. The second molecule can further include a moiety, such as biotin, which is capable of binding a target biomolecule, which in turn can bind to a biomolecule of interest for single molecule fluorescence imaging analysis. Fabrication techniques of the nanoaperture are also provided.

  • Device for measuring nanometer level pattern-dependent binding reactions
    Patent number: 8476065
    Abstract: The present invention is directed to a device comprising (a) a substrate having a surface and (b) an ordered array of posts over the surface, wherein the posts are capable of binding a protein or small molecule ligand, and wherein the pitch between adjacent posts is less than about 100 nm. The invention is also directed to methods for identifying the presence of an analyte in a fluid and to methods for measuring relative binding specificity or affinity between an analyte in a fluid and the posts, using the device of the present invention.

  • METHODS OF FABRICATING ELECTRODES AND USES THEREOF
    Publication number: 20110124188
    Abstract: The present invention relates to methods for fabricating nanoscale electrodes separated by a nanogap, wherein the gap size may be controlled with high precision using a self-aligning aluminum oxide mask, such that the gap width depends upon the thickness of the aluminum oxide mask. The invention also provides methods for using the nanoscale electrodes.
