In Situ Synthesis of Magnetite Nanoparticles in Carrageenan Gels
Daniel-da-Silva, Ana L.; Trindade, T.; Goodfellow, Brian J.; Costa, Benilde F. O.; Correia, Rui N.; Gil, Ana M.Magnetite nanoparticles have been successfully synthesized in the presence of carrageenan polysaccharides using an in situ coprecipitation method. Iron coordination to the sulfate groups of the polysaccharide was confirmed by FTIR. The polysaccharide type (κ, ι, or λ) and concentration have been varied and their effects on particle morphology and chemical stability of the resultant nanocomposite investigated. T...
