David P. Allison 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).

  • Local thermal actuation of material surfaces via micro- and nanowire heating for the prevention of cellular attachment and biological fouling
    Patent number: 10179180
    Abstract: The invention relates in various embodiments to a composite useful as e.g. a medical implant device, and a method of treating fouling, including biofouling as may occur on an implant. The composite comprises a matrix phase and a patterned phase that comprises an energetically activatable wire intermixed with the matrix phase, the wire when energetically activated, which includes thermal activation, causes modification of at least a portion of the matrix phase to treat fouling that might otherwise occur. The method of treating biofouling may be practiced on a patent while the medical implant of the invention is in situ.

  • ACTIVE MATERIALS FOR PREVENTION AND TREATMENT OF FOULED SURFACES
    Publication number: 20140093572
    Abstract: A method, composition and structure to treat fouling. In one embodiment, the method of treating fouling includes providing a structure including a first component of a base material and a second component of an energetically activated nanostructure, and applying a stimuli to the structure that effectuates an increase or decrease in the temperature of the energetically activated nanostructure. The increase or decrease in the temperature of the energetically activated nanostructure modifies the chemical and/or mechanical properties of the base material. The modifications to the chemical and/or mechanical properties of the base material obstruct fouling of the structure.
