Mesoporous Silicate Materials in Sensing
Mesoporous silicas, especially those exhibiting ordered pore systems and uniform pore diameters, have shown great potential for sensing applications in recent years. Morphological control grants them versatility in the method of deployment whether as bulk powders, monoliths, thin films, or embedded in coatings. High surface areas and pore sizes greater than 2 nm make them effective as adsorbent...
متن کاملGated Silica Mesoporous Materials in Sensing Applications
Silica mesoporous supports (SMSs) have a large specific surface area and volume and are particularly exciting vehicles for delivery applications. Such container-like structures can be loaded with numerous different chemical substances, such as drugs and reporters. Gated systems also contain addressable functions at openings of voids, and cargo delivery can be controlled on-command using chemica...
متن کاملA Review: Fundamental Aspects of Silicate Mesoporous Materials
Silicate mesoporous materials have received widespread interest because of their potential applications as supports for catalysis, separation, selective adsorption, novel functional materials, and use as hosts to confine guest molecules, due to their extremely high surface areas combined with large and uniform pore sizes. Over time a constant demand has developed for larger pores with well-defi...
متن کاملPreparation and characterization of multifunctional magnetic mesoporous calcium silicate materials
We have prepared multifunctional magnetic mesoporous Fe-CaSiO3 materials using triblock copolymer (P123) as a structure-directing agent. The effects of Fe substitution on the mesoporous structure, in vitro bioactivity, magnetic heating ability and drug delivery property of mesoporous CaSiO3 materials were investigated. Mesoporous Fe-CaSiO3 materials had similar mesoporous channels (5-6 nm) with...
متن کاملMesoporous silicate materials as substrates for molecular machines and drug delivery
Mesoporous silica thin films and nanoparticles prepared by surfactant-templated sol–gel techniques are versatile substrates that can be easily erivatized with active molecules to create functional materials. By exploiting the chemical and physical differences that exist in different regions f the mesostructure, active molecules can be deliberately placed using one-pot techniques, or they can be...
