Nanoparticles of cerium oxide targeted to an amyloid beta antigen of alzheimer's disease and associated methods
First Claim
1. A method for treating a neurodegenerative disease in a patient in need thereof, the method comprising administering to the patient a therapeutically effective amount of polyethylene glycol (PEG) coated nanoparticles of cerium oxide having an antibody bound thereto, the antibody being specific to an antigen associated with the neurodegenerative disease, wherein the PEG comprises a bifunctional molecule comprising a carboxy terminal and amine terminal, the carboxy terminal being connected to an amine group on the nanoparticles and an amine terminal being connected to the antibody as follows:
- CeO2—
NHCO—
[CH2CH2O]n—
CH2CH2NH-antibody; and
wherein PEG coated nanoparticles are contained in a manufactured medication biologically acceptable for administration to a patient exhibiting symptoms of the neurodegenerative disease.
