Radiolabelling of engineered nanoparticles – different strategies for Ag0-NP, TiO2-NP and MWCNT

Here we present different strategies for the radiolaneling of nanoparticles such as Ag(0), TiO2 and carbon nanotubes. In particular we show the diffusion of radionuclides into Ag(0) and TiO2 nanoparticles, the direct activation of nanoparticles by proton irradiation using a cyclotron, the implantation of Be-7 into nanoparticles by the recoil of the nuclear reaction Li-7(p,n)Be-7 and the radioiodination of carbon nanotubes.
All the methods were characterized with repsect to yield, radiolabel stability and possible change of nanoparticle properties.
