Mesoporous Silica: A Suitable Adsorbent for Amines [PDF]
Nanoscale Research Letters, 2009 Mesoporous silica with KIT-6 structure was investigated as a preconcentrating material in chromatographic systems for ammonia and trimethylamine. Its adsorption capacity was compared to that of existing commercial materials, showing its increased ...

Mesoporous Silica Nanoparticles in Bioimaging [PDF]
Materials, 2020 A biomedical contrast agent serves to enhance the visualisation of a specific (potentially targeted) physiological region. In recent years, mesoporous silica nanoparticles (MSNs) have developed as a flexible imaging platform of tuneable size/morphology, abundant surface chemistry, biocompatibility and otherwise useful physiochemical properties.

Biosafety of Mesoporous Silica Nanoparticles [PDF]
Biomimetics, 2018 Careful analysis of any new nanomedicine device or disposal should be undertaken to comprehensively characterize the new product before application, so that any unintended side effect is minimized. Because of the increasing number of nanotechnology-based drugs, we can anticipate that regulatory authorities might adapt the approval process for ...

Superiority of Mesoporous Silica-Based Amorphous Formulations over Spray-Dried Solid Dispersions
Pharmaceutics, 2022 The aim of this study was to compare the performance of two amorphous formulation strategies: mesoporous silica via solvent impregnation, and solid dispersions by spray drying. Poorly soluble fenofibrate was chosen as the model drug compound.

Mesoporous silica nanoparticles as nanocarriers
Chemical Communications, 2011 Modern nanomedicine aims at delivering drugs or cells specifically to defective cells; therefore, this calls for developing multifunctional nanocarriers for drug delivery and cell-tracking. Mesoporous silica nanoparticles (MSNs) are well suited for this task. In this feature article, we highlight the strategies in the synthesis and functionalization of

Pore Narrowing of Mesoporous Silica Materials [PDF]
Materials, 2013 To use mesoporous silicas as low-k materials, the pore entrances must be really small to avoid diffusion of metals that can increase the dielectric constant of the low-k dielectric. In this paper we present a new method to narrow the pores of mesoporous materials through grafting of a cyclic-bridged organosilane precursor.

Adsorption of Laccase onto Mesoporous Silica Prepared with Inorganic Counterions
Adsorption Science & Technology, 2009 Mesoporous silica has been prepared using tetraethyl orthosilicate (TEOS) as the silica source and cetyltrimethylammonium bromide (CTAB) as the template, with Cl − and SO 2 4 − as the respective inorganic counterions.
