Water Soluble Nanoparticles for the Detection of Radioisotope Activity
Title: Water Soluble Nanoparticles for the Detection of Radioisotope Activity Invention: The invention is scintillant nanoparticles (SNPs), which are core-shell nanoparticles for sensitive detection of radioisotope activity. These SNPs are made from a polystyrene core of variable diameter, with a thin silica shell deposited on the outside of the core. The hydrophobic matrix facilitates energy transfer from the radioisotope to the scintillant dye and increased solubility. Background: Radioisotopes are used as molecular tracers in a variety of assays and liquid scintillation cocktails, which are molded polymers with dyes or inorganic glasses. The trouble with the current nanoparticles is the amount of waste and low penetration depth. Applications:Research institutes who use liquid scintillation countingScintillation proximity assay companiesImaging reagent companies Advantages:SNPs retain a one-year shelf lifeSNPs require less liquid per testSNPs reduce disposal costsSNPs are compatible with current scintillation detector machines, reducing the need to upgrade Licensing Manager: Laura SilvaLauraS@tla.arizona.edu(520) 626-1557
