  • Functionalized polymer hybrids
    Patent number: 9765169
    Abstract: A method of synthesizing a polynucleotide composition includes attaching a compound including at least one initiator or at least one transfer agent for a reversible deactivation radical polymerization to an end of a nucleotide chain assembly immobilized upon a solid phase support during a solid phase synthesis of a polynucleotide so that the initiator or the transfer agent is attacked to the end of a nucleotide chain assembly in a manner which is stable under conditions of deprotection of the polynucleotide, and growing a polymer from the initiator of from a site of the chain transfer agent via the reversible deactivation radical polymerization to form the polynucleotide composition.
    Type: Grant
    Filed: April 17, 2014
    Date of Patent: September 19, 2017
    Assignee: CARNEGIE MELLON UNIVERSITY
    Inventors: Subha Ranjan Das, Saadyah Averick, Sourav K. Dey, Krzysztof Matyjaszewski
