Learning from Biosilica: Nanostructured Silicas and Their Coatings on Substrates by Programmable Approaches

“…In both cases of PEImediated silica mineralization depending on electrospinning fibers and aerogel, however, the characteristic nanostructures due to the PEI crystalline property have not been exploited. Our processing for shaped silicas is remarkably different from conventional silica-fiber formation based on the fibrous aggregates from small-molecule gelators (van Bommel et al, 2003), in which a solution deposition of silica (nontemplated silica) is normally unavoidable because an acidic or basic catalyst is present in solution. Later, a surface mechanism was proposed for silica deposition by designing an organogelator possessing a gelating cholesterol moiety and a catalytic benzylamine residue (van Bommel & Shinkai, 2002), with the silica formation occurring merely on the gel-fiber surface.…”

Molecular Interactions in Natural and Synthetic Self-Assembly Systems

“…From the first reports of Shinkai group (Van Bommel et al, 2003a;Jung & Shinkai, 2004b;Jung et al, 2001c;Jung et al, 2000d;Tamaru et al, 2002e) the strategy was successfully employed and the reported experimental data are summarized and discussed in excellent reviews Yang et al, 2011;Llusar & Sanchez, 2008).…”

Morphology control of silica/poly(methyl methacrylate-co-styrene) hybrid nanoparticles via multiple-miniemulsion approach

“…As a solution, one can force polymer and inorganic phases to interact at a molecular level and upscale the physical properties of the ultimate composite material (7,8). A standard technique for hybrid organic-inorganic material formation uses either hollow particles (9)(10)(11) or capsules (12,13). Due to their ability to encapsulate versatile functional cargos; these methods gained wide applications in catalysis (14), drug-delivery systems (15,16), biology (17), coatings (18,19), and so on.…”
