  • Sorting process of nanoparticles and applications of same
    Patent number: 10717647
    Abstract: A sensing platform includes a substrate, an array of wells formed in the substrate, and sorted nanoparticles filling in the array of wells such that each well contains a single sorted nanoparticle, wherein the sorted nanoparticles are in a cluster state.
    Type: Grant
    Filed: September 26, 2017
    Date of Patent: July 21, 2020
    Assignee: NORTHWESTERN UNIVERSITY
    Inventors: Timothy P. Tyler, Anne-Isabelle Henry, Richard P. Van Duyne, Mark C. Hersam

  • Sorting process of nanoparticles and applications of same
    Patent number: 9802818
    Abstract: In one aspect of the present invention, a method for sorting nanoparticles includes preparing a high-viscosity density gradient medium filled in a container, dispersing nanoparticles into an aqueous solution to form a suspension of the nanoparticles, each nanoparticle having one or more cores and a shell encapsulating the one or more cores, layering the suspension of the nanoparticles on the top of the high-viscosity density gradient medium in the container, and centrifugating the layered suspension of the nanoparticles on the top of the high-viscosity density gradient medium in the container at a predetermined speed for a predetermined period of time to form a gradient of fractions of the nanoparticles along the container, where each fraction comprises nanoparticles in a respective one of aggregation states of the nanoparticles.

  • Isolated polynucleotides having a reduced or an increased content of epigenetic control motifs and uses thereof
    Publication number: 20040097439
    Abstract: The present invention is concerned with modified polynucleotides derived from a native gene and having a reduced or increased number of epigenetic control motifs, at the nucleotide level, as compared to the native gene. These polynucleotides are useful to study, increase and/or reduce genes expression, and to improve DNA vaccination methods. The present invention also relates to methods of using these modified polynucleotides in in vitro and in vivo expression systems.
    Type: Application
