Latest Patents

Xin Qu holds a patent for the "Modification of polymer surfaces as radioisotope carriers." This invention involves creating a radioactive source by forming a polymer layer that is substantially free of inorganic polymers on a substrate material. The polymer layer is then exposed to a radioactive isotope, which is useful for inhibiting restenosis in coronary arteries after procedures such as balloon angioplasty or stent implantation. Specifically, the radioactive source of P, Y, or Ce is deposited on a poly(ethylene terephthalate) (PET) substrate. The process includes coating the substrate with a pH-sensitive hydrogel and adsorbing various amounts of phosphoric acid in aqueous solutions. The substrate is subsequently immersed in P, YCl, or CeCl solutions, allowing for the deposition of P, Y, or Ce on the surface as PPO, YPO, or CePO. To minimize the leakage of the isotope, two different polyurethanes are used to encapsulate and seal the deposited isotopes on the surface.
