M. Scott Long 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).

  • Encapsulation of aqueous phase systems within microscopic volumes
    Patent number: 7803405
    Abstract: A means and method for preparing vesicles and freestanding two-dimensional assemblies using aqueous two-phase systems (ATPS) is described. The surface tension of the ATPS is sufficient to support the assembly of various types of particles, and provide the advantage of being biocompatible with DNA and other types of biological molecules that may be used in the assembly. Vesicles are formed by mixing chemically dissimilar compounds in appropriate concentrations and at a temperature sufficient to form a monophasic mixture. This mixture is then heated above the temperature at which the polymer mixture is monophasic, added to a lipid film, and allowed to hydrate at this elevated temperature.
    Type: Grant
