MSNS abbreviation stands for Mesostructured Silica Nanoparticles. 2012-11-15 · In this work, mesostructured silica nanoparticles (MSN(AP)) with high adsorptivity were prepared by a modification with 3-aminopropyl triethoxysilane (APTES) as a pore expander. The performance of the MSN(AP) was tested by the adsorption of MB in a batch system under varying pH (2-11), adsorbent dosage (0.1-0.5 g L(-1)), and initial MB concentration (5-60 mg L(-1)). 2017-07-01 · Core-shell hierarchical mesostructured silica nanoparticles for gene and chemodrug co-delivery in sequence: We have successfully developed a “chemical homology” strategy for the fabrication of core-shell hierarchical mesostructured MSNs (H-MSNs) with different-sized mesopores and composition-varied frameworks separately in the core and shell. 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 MSNs.
