Multifunctional Nanocomposites Based on Mesoporous Silica: Potential Applications in Biomedicine
In the last decade, significant research efforts were devoted to obtaining materials with welldefined nanostructures for a wide range of applications (Hamley, 2003; Soler-Illia et al., 2002; Paul & Sharma, 2006). Mesoporous silica materials like M41S, HMS, SBAn, FSM, and MSU, among others, are a fairly new type of material that has pores in the mesoscopic range of 2–50 nm (Wan et al., 2007). Th...
متن کاملIonic liquid mediated synthesis and surface modification of multifunctional mesoporous Eu:GdF3 nanoparticles for biomedical applications.
A procedure for the synthesis of multifunctional europium(III)-doped gadolinium(III) fluoride (Eu:GdF3) nanoparticles (~85 nm) with quasispherical shape by precipitation at 120 °C from diethylene glycol solutions containing lanthanide chlorides and an ionic liquid (1-Butyl, 2-methylimidazolium tetrafluoroborate) as fluoride source has been developed. These nanoparticles were polycrystalline and...
متن کاملDissolution of Mesoporous Silica Supports in Aqueous Solutions: Implications for Mesoporous Silica-based Water Treatment Processes.
Under pH 7 - 10 conditions, the mesoporous silica supports proposed for use in water treatment are relatively unstable. In batch experiments conducted in pH 7 solutions, the commonly used support SBA-15 dissolved quickly, releasing approximately 30 mg/L of dissolved silica after 2 hours. In column experiments, more than 45% of an initial mass of 0.25 g SBA-15 dissolved within 2 days when a pH 8...
متن کاملPreparation of magnetic mesoporous silica nanoparticles as a multifunctional platform for potential drug delivery and hyperthermia
We report the preparation of magnetic mesoporous silica (MMS) nanoparticles with the potential multifunctionality of drug delivery and magnetic hyperthermia. Carbon-encapsulated magnetic colloidal nanoparticles (MCN@C) were used to coat mesoporous silica shells for the formation of the core-shell structured MMS nanoparticles (MCN@C/mSiO2), and the rattle-type structured MMS nanoparticles (MCN/m...
متن کاملLyotropic Ferronematic Liquid Crystals Based on New Ni, Cu and Zn Ionic Magnetic Fluids
The properties of lyotropic ferronematic liquid crystals based on new Ni, Cu and Zn ionic magnetic uids are discussed. The eÆciency of these new ferro uids in the lyotropic nematic liquid crystal doping is veri ed and compared with the conventional surfacted ferro uid lyotropic doping. It was observed that the structural characteristics of the lyotropics and ferro uids determine the good format...
