  • Incorporation of biological molecules into bioactive glasses
    Patent number: 5874109
    Abstract: Carriers comprising silica-based glass providing for the controlled release of biologically active molecules, their methods of preparation, and methods of use are disclosed. The carriers are prepared using a sol-gel-derived process. Biologically active molecules are incorporated within the matrix of the glass during production.
    Type: Grant
    Filed: September 4, 1997
    Date of Patent: February 23, 1999
    Assignee: The Trustees of the University of Pennsylvania
    Inventors: Paul Ducheyne, Shulamith Radin, Erick Manuel Santos
