  • HAFNIUM (IV) OXIDE NANOPARTICLES AND AQUEOUS COMPOSITIONS THEREOF
    Publication number: 20250018067
    Abstract: The invention relates to a hafnium (IV) oxide (HfO2) nanoparticle nanocrystal comprising or having a diameter equal or less than (?) 15 nm, stabilized by a plurality of dispersant molecules attached to its surface. The dispersant molecules comprise of a catechol or gallol surface adsorption moiety and an oligo (ethyleneglycol) moiety. The invention further relates to a composition of such nanoparticles in stable colloidal suspension at physiological pH, and the use of the composition in medical treatment and diagnostic applications, particularly to enhance radiotherapy and as an X ray contrast agent. In yet another aspect, the invention provides a method for manufacturing compositions and nanoparticles according to the invention.
