| abstract |
Ligand-modified poly oxo-hydroxy metal ion materials and their uses are disclosed, in particular for nutritional, medical, cosmetic or biologically related applications for example for the treatment of a deficiency related to a component of the material such as anaemia or for the removal of an endogenous substance capable of binding to the material. The preferred metal is ferric iron and the preferred ligands include organic acids such as adipic acid, tartaric acid, succinic acid. In another aspect, processes for preparing the materials and optimising their physicochemical properties and their medical uses. |
