  • Patent number: 11307199
    Abstract: Methods, systems, compositions include biocompatible polymer coated nanoceria that function as aqueous redox catalyst with enhanced activity at an acidic to moderately alkaline pH value between 1 and 8. The compositions are used as oxidizing agents for decomposition, decontamination or inactivation of organic contaminants, such as, pesticides and chemical warfare agents. Another use includes nanoceria as targetable nanocatalyst prepared by conjugating various targeting ligands to the nanoparticle coating to form a colorimetric or fluorescent probe in immunoassays and other molecule binding assays that involve the use of a molecule in solution that changes the color of the solution or emits a fluorescent signal, where localization of nanoceria to organs or tissue is assessed by treatment with an oxidation sensitive dye or other detection devices.

  • Publication number: 20190255101
    Abstract: Differential surface-charge-dependent localization of nanoceria in normal cells and cancer cells plays a critical role in the toxicity profile of a nanoceria particle. Engineered surface-coated cerium oxide nanoparticles with different surface charges that are positive, negative and neutral provide therapeutic results for normal and cancer cell lines. Results show that nanoceria with a positive or neutral charge enters most of the cell lines studied, while nanoceria with a negative charge internalizes mostly in the cancer cell lines. Moreover, upon entry into the cells, nanoceria is localized to different cell compartments (e.g. cytoplasm and lysosomes) depending on the nanoparticle surface charge. The internalization and subcellular localization of nanoceria plays a key role in the nanoparticle cytotoxicity profile, exhibiting significant toxicity when they localize in the lysosomes of the cancer cell lines.

  • Patent number: 9555008
    Abstract: A method of making a hyperbranched amphiphilic polyester compound includes drying under vacuum a mixture of 2-(4-hydroxybutyl)-malonic acid and p-toluene sulphonic acid as catalyst. The vacuum is then released with a dry inert gas after drying. The dried mixture is heated under the inert gas at a temperature sufficient for polymerization. The inert gas is evacuated while continuing to heat the mixture. The formed polymer is then dissolved in dimethylformamide and precipitated out by adding methanol. Modifications of the method yield nanoparticles of polyesters having properties suited for coencapsulating fluorescent dyes together with therapeutic drugs, resulting in theranostic nanoparticles, that is, nanoparticles useful in both therapeutic treatments and diagnostic methods.
