Delia Radulescu 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).

  • Fabrication of drug loaded biodegradable polymer fibers
    Patent number: 7514095
    Abstract: The invention provides tissue engineering compositions and methods wherein three-dimensional matrices for growing cells are prepared for in vitro and in vivo use. The matrices comprise biodegradable polymer fibers capable of the controlled delivery of therapeutic agents. The spatial and temporal distribution of released therapeutic agents is controlled by use of defined nonhomogeneous patterns of therapeutic agents in the matrices.
    Type: Grant
    Filed: December 21, 2004
    Date of Patent: April 7, 2009
    Assignee: Board of Regents, The University of Texas System
    Inventors: Kevin D Nelson, Andres A. Romero-Sanchez, George M. Smith, Nadir Alikacem, Delia Radulescu, Paula Waggoner, Zhibing Hu
  • Method for forming polymer microspheres
    Patent number: 6998074
    Abstract: A method for forming polymer microspheres includes dispensing polymeric material from an orifice of a drop-on-demand ink jet printhead while the orifice is immersed in a solvent extraction media.
