Hyperbranched polyglycerols find increasing usage in biomedicine owing to their excellent biocompatibility like polysaccharides. To prepare hydrogels, they are cross-linked mainly by treating with toxic epoxy reagents. Here we suggest a one-stage nontoxic procedure for the jellification of aqueous solutions that was previously developed for nongelable(More)
To obviate the common precipitation of titania after a precursor addition into aqueous or water-containing solutions, here we are using ethylene glycol as the reaction media with dissolved polysaccharide xanthan. The water is introduced in a restricted amount to provide only the hydration of polysaccharide macromolecules. An introduced precursor is involved(More)
