Sol–gel synthesis and structure of silica hybrid biomaterials

Preparation of the cellulose/silica hybrid containing cationic group by sol–gel crosslinking process and its dyeing properties

“…The silicon dioxide nanoparticles can be synthesized by sol-gel techniques. Recently, the sol-gel method has definitely proved its exceptional potential by providing a possibility of synthesizing a significant number of new materials with high degree of homogeneity and purity at a molecular level and with extraordinary physical and chemical properties (Addamo et al, 2008;Dharmaraj et al, 2006;Lou, Zhang, & Chen, 2003;Samuneva et al, 2008). During the sol-gel process the inorganic mineral, such as tetraethoxysilane (TEOS), is deposited in the cellulose matrix forming hydrogen bond between organic phase and inorganic phase.…”

Organic/Inorganic bioactive materials Part III: in vitro bioactivity of gelatin/silicocarnotite hybrids

“…In other papers we used bioactive glasses in the SiO 2 -3CaO-P 2 O 5 -MgO [40] [43,44]. On the other hand we have also investigated the influence of different silica precursors on the structure of hybrid materials in the presence of HEMA, PEO and Chitin for cell immobilization [45].…”

Biomaterials Obtained by Gelation

“…The difference between these two classes depends on the size of the heterogeneities, which must remain in the submicron range to qualify a biomaterial as a hybrid gel (Catauro et al 2014c). The interest of organic-inorganic hybridization is they permit to design materials with properties which are a synergy of both components (Samuneva et al 2008;Catauro et al 2014c). For instance, the brittle characteristics of the bioceramics can be reduced and flexibility can be added, while keeping a good strength resistance.…”
