It is shown that both polysaccharides form a tight polymer layer surrounding the inorganic particles, which in the case of κ-carrageenan is cross-linked by helical domains forming a self-assembled nanoreactor. The stabilized iron oxyhydroxide particles can undergo further reactions, for example, it is possible by a chemical reaction to produce stabilized magnetite particles. Repetition of the loading/neutralization steps in the reaction results in hybrids with iron contents much higher than the stoichiometric balance of iron and functional groups of the polymer (greater than 100% Fe/SO4−). This combination of high iron content with a natural polysaccharide stabilizer makes these colloids interesting for a number of applications, for example, for nutritional purposes or as contrasting agents for tomography.</dcterms:abstract> <dcterms:title>Iron oxyhydroxide colloids stabilized with polysaccharides</dcterms:title> <dc:creator>Cölfen, Helmut</dc:creator> <dc:creator>Jones, Franca</dc:creator> <dcterms:available rdf:datatype="">2017-11-08T11:01:07Z</dcterms:available> <dc:creator>Antonietti, Markus</dc:creator> <dcterms:isPartOf rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:language>eng</dc:language> <dspace:isPartOfCollection rdf:resource=""/> <dc:date rdf:datatype="">2017-11-08T11:01:07Z</dc:date> </rdf:Description> </rdf:RDF>
