Macroscopic inorganic porous beads are imbibed with a "porous molecular additive" by simple solution processing techniques, resulting in controllable loading and increased surface area. The porous additive consists of soluble organic cage molecules that precipitate as microporous crystals when solutions

To compare the cellular uptake efficiency and cytotoxicity of aminosilane (SiO(2)-NH(2))-coated superparamagnetic iron oxide (SPIO@SiO(2)-NH(2)) nanoparticles with three other types of SPIO nanoparticles coated with SiO(2) (SPIO@SiO(2)), dextran (SPIO@dextran), or bare SPIO in mammalian cell lines. Four types of monodispersed
