Silica-based mesoporous nanoparticles for controlled drug delivery

Journal of Tissue Engineering, 2013
Drug molecules with lack of specificity and solubility lead patients to take high doses of the drug to achieve sufficient therapeutic effects. This is a leading cause of adverse drug reactions, particularly for drugs with narrow therapeutic window or ...

Mesoporous Silica Nanoparticles Inhibit Cellular Respiration

Nano Letters, 2008
We studied the effect of two types of mesoporous silica nanoparticles, MCM-41 and SBA-15, on mitochondrial O 2 consumption (respiration) in HL-60 (myeloid) cells, Jurkat (lymphoid) cells, and isolated mitochondria. SBA-15 inhibited cellular respiration at 25-500 microg/mL; the inhibition was concentration-dependent and time-dependent.

Mesoporous Silica Nanoparticle Nanocarriers: Biofunctionality and Biocompatibility [PDF]

Accounts of Chemical Research, 2013
The study of ordered mesoporous silica materials has exploded since their discovery by Mobil researchers 20 years ago. The ability to make uniformly sized, porous, and dispersible nanoparticles using colloidal chemistry and evaporation-induced self-assembly has led to many applications of mesoporous silica nanoparticles (MSNPs) as "nanocarriers" for ...

Spontaneously formed porous and composite materials [PDF]

, 2010
In recent years, a number of routes to porous materials have been developed which do not involve the use of pre-formed templates or structure-directing agents. These routes are usually spontaneous, meaning they are thermodynamically downhill.
