While cancer still represents one of the most serious threats to human health, a boom of nanoparticle applications has been experienced in medicine in the last decade, in the fields of both diagnostics and therapy [reviewed in (1-5)]. Hence, it is not surprising that in order to fight malignant diseases a veritable ‘ZOO’ of nanoparticles is being investigated (6).
