Mesostructured silica nanoparticles

The surface of α-Fe2O3 nanoparticles was successfully coated with mesostructured silica templated by surfactant assemblies using cetyltrimethylammonium ions. By repeating the coating operation, it was possible to control the thickness of the mesostructured silica phase. Abstract: Mesoporous silica nanoparticles (MSNs) have garnered a great deal of attention as potential carriers for therapeutic payloads. Here, we report a pH-responsive drug-carrier based on chondroitin sulfate functionalized mesostructured silica nanoparticles (NMChS-MSNs) ie, the amidation between NMChS macromer and amino group functionalized and unfunctionalized silica nanoparticles. At a low con-centration (<100 μg/mL), LP-MSN-P has low cytotoxicity. Moreover, we also demonstrate that the LP-MSN-P can eﬀectively deliver siRNA into cancer cells and silence the oncogenes.
