Mesoporous silica nanoparticles in nanomedicine applications [PDF]

open access: yesJournal of Materials Science: Materials in Medicine, 2018
In the last few years mesoporous silica nanoparticles (MSNs) have gained the attention of the nanomedicine research community, especially for the potential treatment of cancer. Although this topic has been reviewed before, periodic updates on such a hot topic are necessary due to the dynamic character of this field.

Bilirubin adsorption property of mesoporous silica and amine-grafted mesoporous silica [PDF]

open access: yesNano-Micro Letters, 2009
Abstract Nephritic, hepatic and immune failures would lead to the overload of endogenous toxic molecules (e.g. bilirubin, cholic acid, uric acid, creatinine etc.) in human bodies. It is fatal in most cases and extracorporeal blood purification (ECBP) is powerful first-aid therapy. Adsorbents are key parts of ECBP apparatus. Mesoporous silicas
