Abstract:
A method for producing superparamagnetic nanostructures comprising,a) preparing a block copolymer solution containing an amphiphilic block copolymer; b) preparing a sol-gel precursor containing a silicon-containing compound; c) adding an iron precursor to said amphiphilic block copolymer solution or to said sol-gel precursor; d) mixing said block copolymer solution and said sol-gel precursor to form a hybrid inorganic nanostructured material; e) removing a solvent from said hybrid inorganic nanostructured material to form a individual nanostructured material; and f) calcinating said individual nanostructured material to form a superparamagnetic nanostructure material.
