Abstract

To further our understanding of nanoparticle interactions with biological systems, it is important that highly sensitive, reliable and robust methods for labelling particles are established. We report here the application of a series of bi-functional cage ligands to radiolabel a range (i.e. shapes and sizes) of titanium dioxide (TiO2) particles. The cages were covalently attached to the surface of the particles via the use of a dopac derivative and then radiolabeled with a gamma emitting radioisotope. The final radiolabeled nanoparticles proved to be stable in solution and the method easy and robust. The application of a gamma emitter allows the radiolabeled particles to be tracked in vivo and in the environment.
