Preparation of novel magnetic hollow mesoporous silica microspheres and their efficient adsorption

Mesoporous silica hollow capsules embedded with magnetic nanoparticles

“…However, our preparation method of the mMSHCs provided the Ms value comparable to the reported magnetic capsules [8][9][10][11][12][13][14][15][16][17][18]. As shown in Figure 6(b), the Ms value of our mMSHCs was large enough to show a magnetic separation using a neodymium magnet.…”

“…Specifically, the magnetic properties allow the magnetically-guided drug delivery for the therapy and the contrast-enhanced magnetic resonance imaging for the diagnosis. So far, various types of mMSHCs have been reported; the mMSHC incorporating the mNPs on the outer surface of the shell [7], inside the shell [8,9], or in the hollow cavity [10][11][12] and the rattle-type mMSHC that encapsulates one magnetic particle in its hollow cavity [13][14][15][16][17][18].…”

Fabrication of high specificity hollow mesoporous silica nanoparticles assisted by Eudragit for targeted drug delivery

“…Hollow mesoporous silica nanoparticles (HMSNs) with large hollow interiors and through pores in the shell are exceptionally promising platforms for various current and emerging applications such as pharmaceutics [1,2], optics [3], environmental protection [4,5] and catalysis [6]. In particular, they have been exploited as nanocarriers for drug delivery [7,8] because their big cavities provide large drug loading capacities [9] and their open mesopores allow for controlled transportation of drugs [10].…”

Synergistic Removal of Pb(II), Cd(II) and Humic Acid by Fe3O4@Mesoporous Silica-Graphene Oxide Composites

“…In this way, the development of adsorbents with high adsorption capacity, low toxicity, and efficient separation has attracted considerable interest. [10], [11].…”
