Can cadmium nanoparticles be safe?

Abstract:
Are cadium-containing fluorescent nanoparticles toxic to cells? That seems to depend sensitively on what the cadmium-based semiconductor is coated with.

Wolfgang Parak of the Ludwig Maximilians University in Munich and co-workers say that the 'leakage' of cadmium ions from such particles isn't the only way that they can damage or kill cells.

So they say that any study of the potential hazards of nanoparticles in biological research and biomedical applications will have to take careful note of exactly where the particles end up when in contact with living cells —whether, for example, they are ingested into the cells, stuck to the cell surface, or simply floating freely outside the cells.
