Iron-containing nanoparticles based on the 2-hydroxypropyl-β-cyclodextrin in aqueous solutions

The water-soluble hybrid nanoparticles based on high-substituted 2-hydroxypropyl-β-cyclodextrin were formed in situ during the reduction of iron(+2) salts by hypophosphite ion in alkaline medium. These nanoparticles are high sensitive to temperature and ultrasonication. It was established that the temperature and ultrasonication time of exposure increase leads to the successive dissociation of the nanoparticles.
