  • Publication number: 20230248659
    Abstract: An immune-suppressing nanoparticle (NP) decorated with alpha-1 acid glycoprotein (AGP), an anti-inflammatory protein, circumventing the resistance of breast tumor cells to chemotherapy in addition to suppressing the tumor metastasis and invasion is disclosed. Methods of making hyaluronic acid-chitosan nanoparticles decorated with AGP (AGP-HA NPs) by sequential ionic gelation, spray drying, and AGP-surface adsorption are also disclosed. Treatment options to strengthen the anti-cancer effects of chemotherapeutic agents and potentially improve the survival rate of patients with metastatic breast cancer using the disclosed AGP-HA NPs containing agents are also disclosed.

  • Publication number: 20210401934
    Abstract: A protein functionalized anti-inflammatory nanoparticle and a method of preparing the protein functionalized anti-inflammatory nanoparticle is disclosed. The protein functionalized anti-inflammatory nanoparticle includes a central core comprising a hyaluronic acid coated chitosan nanoparticle and surface adsorbed anti-inflammatory proteins forming an outer shell around the central core, wherein the surface adsorbed anti-inflammatory protein is AGP (alpha-1-acid glycoprotein). The method of preparation includes dispersing chitosan nanoparticles in acetic acid/acetate buffer to produce a dispersion, adding an equal amount of acetate buffer containing hyaluronic acid under vigorous stirring to form hyaluronic coated chitosan nanoparticle (HA-CS) and functionalizing the hyaluronic coated chitosan nanoparticle with surface adsorbing anti-inflammatory protein AGP, to form the protein functionalized anti-inflammatory nanoparticle.

  • Patent number: 10774095
    Abstract: The invention provides metal-ascorbic acid crystals and a method for synthesizing the metal-ascorbic acid crystals. The metal in the metal-ascorbic acid crystals is one of copper (Cu), gold (Au) and silver (Ag). The method for synthesizing the metal-ascorbic acid crystals includes sonicating a solution of ascorbic acid and a solvent in dark to obtain a clear solution, wherein the solvent is one of dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). A metal salt is added to the clear solution, wherein the metal salt is one of copper (II) sulfate pentahydrate (CuSO4.5H2O), gold (III)-chloride (AuCl3), and silver sulfate (Ag2SO4). The clear solution is sonicated after adding the metal salt to obtain a reaction mixture. Thereafter, the reaction mixture is heated in dark. The reaction mixture is treated to facilitate solvent extraction of the metal-ascorbic acid. Finally, the metal-ascorbic acid is crystallized.
