Latest Patents

Hongjuan Ma holds a patent for an "Engineered radioactive polymeric microsphere, and preparation and application thereof." This invention involves a detailed preparation method that includes adding a styrene monomer and a disperser and/or a crosslinker into a medium. The process continues with the feeding of nitrogen or helium and stirring to obtain a first reaction mixture. The first reaction mixture is then heated, and an initiator is added, followed by a reaction under stirring at a constant temperature to obtain a second reaction mixture. The second reaction mixture undergoes washing with ethanol and water, followed by vacuum drying to yield a crude polymeric microsphere. This crude microsphere is subjected to radiation-induced graft polymerization with a functional monomer to create a functionalized polymeric microsphere. Finally, the functionalized microsphere is exposed to a radionuclide to prepare the engineered radioactive polymeric microsphere.
