Stealth-cap technology for light-emitting nanoparticles

Scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in collaboration with the Monash University Australia, have succeeded in significantly increasing the stability and biocompatibility of special light-transducing nanoparticles. They have developed so-called "upconverting" nanoparticles that not only convert infrared light into UV-visible light, but also are water-soluble, remain stable in complex body fluids, and can be used to store medications. They have created a tool that could potentially make the fight against cancer more effective.
