Mesoporous silica nanoparticles in nanotechnology

Critical Reviews in Biotechnology, 2012
Mesoporous silica nanoparticles (MSNs) are a versatile drug delivery system that can be used for loading of different guest molecules such as peptides, proteins, anticancer agents, and genetic material. MSNs are considered promising drug carriers due to their tuneable particle size, pore structure, and surface functionalization.

Ultrabright Fluorescent Mesoporous Silica Nanoparticles

Small, 2010
AbstractThe first successful approach to synthesizing ultrabright fluorescent mesoporous silica nanoparticles is reported. Fluorescent dye is physically entrapped inside nanochannels of a silica matrix created during templated sol–gel self‐assembly. The problem of dye leakage from open channels is solved by incorporation of hydrophobic groups in the ...

Dodecagonal tiling in mesoporous silica

Nature, 2012
Recent advances in the fabrication of quasicrystals in soft matter systems have increased the length scales for quasicrystals into the mesoscale range (20 to 500 ångströms). Thus far, dendritic liquid crystals, ABC-star polymers, colloids and inorganic nanoparticles have been reported to yield quasicrystals.

Mesoporous silica spheres from colloids

Journal of Colloid and Interface Science, 2007
A novel method has been developed to synthesize mesoporous silica spheres using commercial silica colloids (SNOWTEX) as precursors and electrolytes (ammonium nitrate and sodium chloride) as destabilizers. Crosslinked polyacrylamide hydrogel was used as a temporary barrier to obtain dispersible spherical mesoporous silica particles.

Cytotoxicity of mesoporous silica nanomaterials

Journal of Inorganic Biochemistry, 2008
We here measure the toxicity of MCM-41, a mesoporous silica nanomaterial, two of its functionalized analogs, AP-T, which has grafted aminopropyl groups and MP-T, which has grafted mercaptopropyl groups, and spherical silica nanoparticles (SiO(2)), toward human neuroblastoma (SK-N-SH) cells.

Reversible replication between ordered mesoporous silica and mesoporous carbon

Chemical Communications, 2002
Highly ordered mesoporous silica can be regenerated from a mesoporous carbon CMK-3 that is a negative replica of mesoporous silica SBA-15, indicating reversible replication between carbon and inorganic materials.

Talented Mesoporous Silica Nanoparticles

Chemistry of Materials, 2016
The structure and functionality of mesoporous silica nanoparticles can be tuned by means of numerous and diverse synthetic strategies. Focusing on experimental methods, we describe how pore size and pore topology of the mesopore system can be modified through templating and pore-swelling agents, as well as different synthesis conditions.
