  • Method for measuring carbon nanotubes taken-up by a plurality of living cells
    Patent number: 8632671
    Abstract: The present invention provides methods, apparatuses and kits for determining the presence and the concentration of nanoparticles in a given area, solution or region via cellular uptake and/or adsorption monitored through laboratory equipment. For example, the present invention provides a method of quantifying one or more nanoparticles by incubating a nanoparticle solution comprising one or more nanoparticles with one or more cells; isolating the one or more cells; lysing the one or more cells to release a cell lysate; separating the cell lysate electrophoretically on a gel; digitizing the gel to form a gel image; quantifying the nanoparticle intensity in the gel image; and correlating the nanoparticle intensity to a cell-associated nanoparticle concentration.
    Type: Grant
    Filed: October 2, 2009
    Date of Patent: January 21, 2014
    Assignee: Board of Regents, University of Texas System
    Inventors: Rockford K. Draper, Paul Pantano, Ru-Hung Wang, Carole Mikoryak
  • Diameter-selective reversible closable peptides
