  • Small water-soluble quantum dots
    Patent number: 9229006
    Abstract: Water-soluble, stable fluorescent PEGylated alkanethiol-coated quantum dots are made by contacting quantum dots with PEGylated alkanethiol in a non-oxidative, water-immiscible organic reaction solvent under a non-oxidative gas, wherein the reaction solvent is in contact with an aqueous phase, at elevated temperature and time sufficient to coat the dots with the PEGylated alkanethiol, wherein resultant water-soluble, stable fluorescent PEGylated alkanethiol-coated dots enter the aqueous phase.
    Type: Grant
    Filed: February 19, 2014
    Date of Patent: January 5, 2016
    Assignee: Board of Trustees of the University of Illinois
    Inventors: Paul R Selvin, Pinghua Ge
