“…For these reasons, SBA-15 has received great attention in surface and materials sciences with its prominent applications in nanocomposites, catalysis, and separations [2]. For certain applications, including enzyme immobilization [3], drug release [4], adsorption of vapors [5], and chromatographic stationary phases [6,7] hydrophobic surfaces are needed; this requires surface functionalization of hydrophilic bare SBA-15. The classical method of covalent functionalization of silicas includes grafting through reactions with organosilanes of the general formula R 4Àn SiX n (n = 1 À 3).…”

“…This interest arises from their exceptional textural properties such as a regular channel arrangement, a size of pores higher than in zeolites structures, and scalable from 2 to 30 nm, as well as the specific surface areas that can exceed 1000 m 2 g −1 for some classes of materials. The physicochemical characteristics of these materials allow then their use in varied areas such as catalysis [6], adsorption [7], separation [8], chromatography [9][10], and biochemistry as a carrier for enzyme immobilization [11] or drug release [12]. Mesoporous silicas consist in a frame of amorphous silica delimiting channels and/or wellordered cavities of regular sizes.…”
“…It has a more stable structure, more tolerant of a wider range of environments, greater resistance to organic solvents properties and has been explored extensively for the size selective immobilization and adsorption of large biomolecules [16,17]. However, an extra surface modification was usually needed to enhance the adsorption selectivity of biomolecules [18][19][20][21][22][23][24].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
