Malcolm J. Fraser, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10287578
    Abstract: The present invention relates to DNAzymes (also known as deoxyribozymes, DNA enzymes, catalytic DNA, or DZ), which are conjugated to nanoparticles (NP) to facilitate the detection of nucleic acids. One aspect of the invention relates to compounds comprising DNAzymes conjugated to nanoparticles (DZ-NP), such as metallic or gold nanoparticles, and methods for their synthesis. Another aspect of the invention relates to methods of using the conjugated compounds to detect nucleic acids, such as genomic material or transcripts of infectious agents, such as viruses, exemplified by applications demonstrating visual detection of Flavivirus RNA molecules, such as dengue virus, or Alphavirus RNA molecules, such as chikungunya virus, in short time periods, using compositions comprising stable components.
    Type: Grant
    Filed: June 16, 2014
    Date of Patent: May 14, 2019
    Assignee: The University of Notre Dame
    Inventors: James Carter, Malcolm J. Fraser, Jr.

  • Patent number: 7105343
    Abstract: The present invention provides efficient transfer of genes into host cells or embryos to transform the cells or embryos by transposition vectors using the minimal amount of nucleotide sequences in the transposon piggyBac required for gene transfer. The transformed cells or embryos may also be developed into transgenic organisms.
    Type: Grant

    Assignee: University of Notre Dame du Lac
    Inventors: Malcolm J. Fraser, Jr., Xu Li
  • Patent number: 6218185
    Abstract: The present invention is directed to nucleic acid and amino acid sequences for transformation constructs containing piggyBac or tagalong transposable elements. These constructs allow for the precise excision and insertion of heterologous DNA into a host cell.
