Jung-Hyurk Lim 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).

  • Peptide and protein arrays and direct-write lithographic printing of peptides and proteins
    Patent number: 7842344
    Abstract: The present invention relates to the use of direct-write lithographic printing of proteins and peptides onto surfaces. In particular, the present invention relates to methods for creating protein and peptide arrays and compositions derived therefrom. Nanoscopic tips can be used to deposit the peptide or protein onto the surface to produce a pattern. The pattern can be dots or lines having dot diameter and line width of less than 1,000 nm. The tips and the substrate surfaces can be adapted for the peptide and protein lithography.
    Type: Grant
    Filed: March 1, 2004
    Date of Patent: November 30, 2010
    Assignee: Northwestern University
    Inventors: Chad A. Mirkin, Jung-Hyurk Lim, David S. Ginger, Jwa-Min Nam, Ki-Bum Lee, Linette Demers, Albena Ivanisevic
  • Electrostatically driven lithography
    Patent number: 7102656
    Abstract: A method of nanolithography includes transporting a patterning compound from a nanoscopic tip to a substrate to form a pattern on the substrate. The patterning compound has a first electrostatic charge and the substrate has a second electrostatic charge which is opposite to the first electrostatic charge. The patterning compound can be an electrically conductive polymer having a charged polymer backbone. The patterns can be dots and lines having lateral dimensions of less than one micron. No electrical bias from an external voltage source between the tip and the substrate is needed.
