Diatomite is a natural porous silica material of sedimentary origin, formed by remainsof diatom skeletons called "frustules." The abundance in many areas of the world andthe peculiar physico-chemical properties made diatomite an intriguing material forseveral applications ranging from food production to pharmaceutics. However,diatomite is a material still rarely used in biomedical applications. In this chapter, theproperties of diatom frustules reduced to nanoparticles, with an average diameter lessthan 350 nm, as potential drug vectors are described. Their biocompatibility, cellularuptake, and capability to transport molecules inside cancer cells are discussed.Preliminary studies of in vivo toxicity are also presented.
