A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising cerous ion, citric acid and ethylenediaminetetraacetic acid in a predetermined ratio, an oxidant, and water is provided along with temperature conditions to directly form, without isolation, a stable dispersion of cerium oxide nanoparticles. These biocompatible cerium oxide nanoparticles may be used to prevent and/or treat oxidative stress related diseases, such as stroke, relapse/remitting multiple sclerosis, chronic-progressive multiple sclerosis, amyotrophic lateral sclerosis, and ischemic reperfusion injury.

Nanoceria for neutralizing free radicals

Nanoceria for the treatment of oxidative stress

A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising a metal ion, a nucleobase, an oxidant, and water, is provided along with temperature conditions to directly form within the reaction mixture, a stable dispersion of nanoparticles. Biocompatible nanoparticles comprised of cerium or iron as the metal ion, and a purine and/or a pyrimidine as the nucleobase, are described.

Nanoparticles of a metal and a nucleobase

A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising cerous ion, citric acid, an oxidant, and water, is adjusted to a predetermined range of pH, held at temperature conditions to directly form, without isolation, a stable dispersion of cerium oxide nanoparticles. Dispersions of these biocompatible cerium oxide nanoparticles exhibit self-life well in excess of one year, and may be used to prevent and/or treat disease or injury, such as oxidative stress related diseases and events.

Nanoceria with citric acid additive

A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising a metal ion, a biguanide, an oxidant, and water; optionally further comprising an alpha-amino acid or a nucleobase; is provided along with temperature conditions to directly form within the reaction mixture, a stable dispersion of metal-containing nanoparticles. Biocompatible nanoparticles comprised of cerium and a biguanide, and optionally containing an alpha-amino acid or a nucleobase, are also described. The use of metal oxide nanoparticles comprising a biguanide as a nanoparticle core/corona in the preparation of nanoscale ionic (liquid) material compositions is disclosed.

Nanoparticles of a metal and a biguanide

A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising cerous ion, an &#x3b1;-amino acid, an oxidant and water is provided along with temperature conditions to effectively form nanoparticles. These biocompatible nanoparticles may be further conjugated to biologically active agents, such as plasmid DNA, siRNA or proteins, such that a cell transfection agent is formed.
