Fibers drawn from a viscous dextran so- 28 H. Cölfen lution with silicalite nanoparticles led to aligned silicalite nanocrystal fibers, with subsequent removal of the dextran template [216]. A similar approach, but with a dextran sulfate solution template and amino-acid coated hydroxyapatite nanoparticles, could be used to generate hydroxyapatite sponges, which showed promising properties for cartilage and soft tissue engineering [218]. Elevated temperatures were also applied in a hydrothermal approach using starch and other polysaccharides for the production of carbon-coated silver nanocables with remarkably uniform core and shell diameters and interconnection points [219].

Nevertheless, the proposed virtual phase diagram means that under isothermal conditions and constant Ca2+ concentration, formation of the experimentally observed spherical hydrated ACC particles of the postulated liquid character will begin at the binodal at point B Fig. 10 Schematic virtual phase diagram that explains the formation of spherical particles by liquid–liquid phase segregation. Reproduced from [142] with permission of Wiley 22 H. Cölfen in Fig. 10 up to the spinodal decomposition point C under simultaneous formation of a highly concentrated CaCO3 phase in water.

Silica nanospheres and their networks can form in vitro within seconds when silaffins are added to a solution of silicic acid, implying the catalytic role of the silaffins for the silica polycondensation. The morphology of precipitated silica particles can be controlled by changing the chain length of the polyamines as well as by a synergetic action of long-chain polyamines and silaffins [222]. The results imply that similar mixtures are Fig. 11 a SEM image of the nanocables with encapsulated pentagonal silver nanowires.
