Synthesis ormosils

On the basis of the sol-gel process, much more attention has been paid to silicate-containing Class II hybrids, also referred to as organically modified silicas, ormosils. In this section, the synthesis of some of the most characteristic ormosils for bone and dental applications are described. 

Fig. 12.7 Some examples of network formers and network modifiers used for the synthesis of ormosils.

It is known that the advantages of imprinted ormosils (organically modified silanes) over acrylic-based MIPs are their chemical stability, the high thermal stability of sol-gel materials, synthesis in mild temperature conditions, optical transparency, photo-, electro- and chemical stability, all properties that made these materials ideal for use in optical sensing approaches, particularly in aqueous samples.48 50 Although... 

The production of polyacrylamide nanoparticles is based on a water-in-oil (W/0) microemulsion technique 40). The silica nanoparticles are prepared by a modified Stober method (75). The ormosil nanoplatform is prepared by a two-step method based on sol-gel process 24,41). The poly decylmethacrylate nanoplatform is prepared by emulsion polymerization 27,42). Encapsulation of drugs or nanocrystals into nanoparticles was made by adding these components to the reaction mixture at the beginning of, or during, the synthesis. Covalent...
