“…For example, MCM-41, which is surface functionalized with glycidoxy groups, exhibited enhanced binding efficiency and stability as a protein carrier in antibody purification chromatography [23]. Organo-functionalized MPS fabricated for biosensors enhances the catalytic activity and stability of immobilized enzymes [24,25]. These types of MPSs are often used as metal ion adsorption materials.…”

a b s t r a c tNovel mesoporous silica sheets with surface amino-functional groups (sheet-NH 2 ) were prepared for the efficient adsorption of aqueous metal ions. The sheet-NH 2 were synthesized by a dual-templating process using Pluronic P123 and N-palmitoyl-l-alanine as templates. Two silicone regents were used to form the silica framework: tetraethoxysilane and 3-aminopropyltriethoxysilane. In the synthetic process, the as-prepared silicate was refluxed in ethanol to remove the organic templates remaining from the surface amino groups derived from APTES. The prepared sheet-NH 2 showed widths of several micrometres and small thicknesses of approximately 50 nm. The pore diameter, pore volume and BET surface area of sheet-NH 2 were determined by nitrogen adsorption-desorption isotherms to be 3.1 nm, 0.73 cm 3 g −1 and 189.9 m 2 g −1 , respectively. TEM, XRD, FT-IR and TG-DTA analysis demonstrated that the sheet material had a disordered mesoporous structure and contained organic chains. The adsorptions of aqueous zinc(II) and copper(II) metal ions were examined and compared with amino-functionalized conventional mesoporous silica (MCM-NH 2 ), calcined mesoporous silica sheets and silica beads with no porous structures. Notably, the sheet-NH 2 exhibited the highest adsorption of both zinc and copper ions among the examined materials. In addition, the metal ion sorption equilibrium data of sheet-NH 2 were fitted to the Langmuir isotherm model.

“…[67,70] For example, Shimomura et al [67] reported a facile approach for the development of the first electrochemical amperometric biosensor for detecting formaldehyde even at low concentrations based on enzyme immobilization in mesoporous silica materials. Kato et al [68] developed formaldehyde biosensors with small size and high sensitivity by immobilization of formaldehyde dehydrogenase on the functionalized mesoporous silica.…”

Silica has become a common platform for various catalytic and chemical reactions, biosensor, and drug release owing to its low toxicity, chemical and physical stabilities, large surface area, tunable pore sizes, and well-defined surface chemistry. Therefore, biomolecules encapsulated within a porous silica host has provoked significant interest in the development, application, and market of silica-based biosensors due to its potential application in analytic chemistry and biological science. Considerable progresses have been achieved in past few decades. This review focuses primarily on such advances in synthesis and applications of silica-based biosensors, especially emphasizing development which has occurred in the last 10 years, further driving readers to understand and construct various silica-based biosensors with high sensitivity and high stability.

Silica-based mesostructured nanomaterials have emerged as a full family of biomaterials with tremendous potential to address the requirements for the bone regeneration process. This review focuses on more recent advances in bone regeneration process based on silica-based mesoporous biomaterials during 2012 to January 2015. In this review, we describe application of silica-based mesoporous mesostructured nanomaterials (possessing pore sizes in the range 2-50 nm) for the bone regeneration process. We summarize the preparation methods, the effect of mesopore templates and composition on the mesopore-structure characteristics, and different forms of these materials, including particles, fibers, spheres, scaffolds, and composites. The effect of structural and textural properties of mesoporous materials on the development of new biomaterials for treatment of different bone pathologies such as infection, osteoporosis, cancer, and so forth is discussed. In addition, silica-based mesoporous bioactive glass, as a potential drug/growth factor carrier, is reviewed, which includes the composition-structure-drug delivery relationship and the functional effect on the antibacteria and tissue-stimulation properties. Also, application of different mesoporous materials on construction of 3D macroporous scaffolds for bone tissue engineering was disused. Finally, this review discusses the possibility of covalently grafting different osteoinductive agents to the silica-based mesoporous scaffold surface that act as attracting signals for bone cells to promote the bone regeneration process.
