Suram T. Pathirana 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).

  • Use of pullulan to isolate and preserve biological material
    Patent number: 7604807
    Abstract: Compositions and methods for the reversible preservation of biological samples are provided. The compositions include natural polymers such as pullulan or acacia gum, including derivations and modifications thereof, which are usefull as a reversible preservation solution. A method is provided for using pullulan or Acacia Gum to isolate and reversibly preserve a biological specimen in a dormant state at room temperature for an extended period with minimal damage to the specimen. The compositions and methods disclosed may also be used to create reversibly preserved biological specimens and biological receptors for use in biosensors.
    Type: Grant
    Filed: January 27, 2006
    Date of Patent: October 20, 2009
    Assignee: Auburn University
    Inventors: Vitaly J. Vodyanoy, James M. Barbaree, Bryan A. Chin, William Charles Neely, Suram T. Pathirana, Timothy D. Braden
  • Use of acacia gum to isolate and preserve a biological receptor on a biosensor
    Patent number: 7473550
    Abstract: Compositions and methods for the reversible preservation of biological samples are provided.

  • Ligand sensor devices and uses thereof
    Patent number: 7138238
    Abstract: Methods and compositions for evaluating the affinity of one or more ligands of interest are provided. In particular, a ligand sensor device (LSD) comprising a sensor coupled to a peptide of interest is provided. Assays using the LSD allow detection of ligand-peptide interactions directly in tissue samples and thus provide an in vitro assay to characterize peptide ligands. The LSD and assays find particular use in characterizing cell-specific peptides isolated from in vivo screening in animals to determine their suitability for use in human therapy.
