Researchers in Germany have developed radiolabeled gold nanoparticles for application in studies designed to evaluate how the particles function in biological systems. The gold radioisotope has a 186-day half-life, which makes it useful for long-term biokinetic studies, according to the report published in the Journal of Nanoparticle Research. Researchers said the nanoparticles can be stable for several hours, meaning they are useful for risk assessments.
