“…The fact that a very wide range of simple LMWG can be readily synthesised means that their structure can be readily adapted to tune their solubility allowing access to a huge range of organogels as crystallization media. In general, while there are a few reports of crystallization from non-aqueous media such as the crystallization of 1 : 1 complexes of quinones with hydroquinones out of Sephadex LH.20 (an alkylated cross-linked dextran) or the crystallization of silver bromide from polyvinyl chloride in dimethyl sulfoxide, 36 organogels are highly underutilised as crystal growth media. LMWG also offer the potential to synthesise gelators that match the chemical structure of the crystallization substrate and hence provide an active nucleation surface.…”

Spatial Control of Crystal Nucleation in Agarose Gel

2009

Spatial and temporal control of crystal nucleation is demonstrated by nonphotochemical laser-induced nucleation of an aqueous agarose gel prepared with supersaturated potassium chloride. The location of nucleation was controlled by means of an optical mask; crystals were only observed in the area exposed to near-infrared laser radiation. The dependence of nucleation on laser power was measured, and the results suggest that the agarose gel reduces the effective supersaturation of the aqueous potassium chloride.

“…10 Very possibly, by selecting gel-crystal pairs and growth conditions, more and more crystals will be found to incorporate gel media. In order to expand the diversity of organic crystals that can be grown in gels, future work will need to consider using gels formed in organic solvents (organogels) 11 as matrices.…”
