“…A wide variety of ionic or non-ionic surfactants and copolymers can be utilized in this process. The diversity of surfactants and copolymer systems has led to a wide variety of organized structures including micelles [21][22][23][24][25][26][27] , vesicles [28][29][30] , and ionic (lyotropic) liquid crystals [31][32][33][34] to be utilized as soft templates in the synthesis of microporous and mesoporous silica nanostructures, tailor made to suit individual research needs. These methods are often simpler than those using hard templates, often accomplished by a one pot synthesis with the easy removal of the template after the reaction.…”

Microporous silica nanoparticles have been developed by a reverse microemulsion method utilizing zinc nanoclusters encapsulated hydroxyl-terminated polyamidoamine (PAMAM-OH) dendrimers as a soft template and made tunable within the outer diameter range of 20-50 nm with a core mesopore of 2-15 nm. Synthesized nanoparticles were used to study the effects of surface area and microporous volumes on the vibrational spectroscopy of water. These spectra reveal contributions from bulk interfacial/interparticle water, ice-like surface water, liquid-like water, and hydrated silica surfaces suggesting that microporous silica nanoparticles allow a way to probe silica water interactions at the molecular scale.
