Patent number: 7981972Abstract: A synthetic graft has a glass composition comprises silicon as a network former and Sr as a stable isotope acting as a network modifier. The composition contains calcium as a network modifier and Zn acting as a as either a network modifier or as a network former. The glass composition may be mixed with a solution of polyalkenoic acid to provide advantageous glass polyalkenoate cements (GPCs). These cements are particularly effective for use as bone cements and fillers in the human skeleton as they set at room temperature, have similar strengths to bone, chemically bond to both bone and surgical metal, and release therapeutic ions, which can assist in wound healing and bone re-growth.Type: GrantFiled: July 31, 2006Date of Patent: July 19, 2011Assignee: University of LimerickInventors: Mark Robert Towler, Daniel Boyd

Patent number: 7973094Abstract: A metal nanoparticle supported on or dispersed in a polymer is irradiated with photons from a laser source to address the nanoparticles. The polymer is transmissive to the photons and addressed nanoparticles transform the energy of the photon to heat which is transferred to a material in the vicinity of the nanoparticle. The locally heated material undergoes a physical or chemical transformation upon heating. The transformed material can be a material in the proximity of the metal nanoparticle supported polymer or metal nanoparticle/polymer composite. In this manner thermally induced physical or chemical transformations can be carried out in very small volumes of material without significant heating to the bulk of the material.Type: GrantFiled: June 28, 2007Date of Patent: July 5, 2011Assignee: University of Central Florida Research Foundation, Inc.Inventors: Qun Huo, Jianhua Zou, Hui Chen
