Methods, materials, and systems for treating injuries to the central nervous system using light emitting nanoparticles
The present invention relates to the use of light-emitting, water soluble nanoparticles in the treatment of disorders of the central nervous system.
1. A method for treating a disorder of the central nervous system in a subject suffering from a central nervous system injury, such method comprising:
a) activating synthetic, light-emitting, water soluble nanoparticles to create activated light-emitting nanoparticles; and
b) administering to said subject a composition comprising said activated light-emitting nanoparticles;
wherein the activated light-emitting nanoparticles emit light in the infra-red or near infra-red spectrum.
2. The method of claim 1 , where the disorder of the central nervous system is the result of an ischemic stroke.
3. The method of claim 1 , wherein the disorder of the central nervous system is the result of an impact to the head.
4. The method of claim 1 , wherein the nanoparticles are selected from the group consisting of quantum dots, silica nanoparticles, magnetic iron oxide “nanoworms,” Cr3+/Pr3+ co-doped zinc gallogermanate, and gold nanoparticles.
5. A method for treating or preventing oxidative damage to mitochondria following reperfusion in a subject suffering from a central nervous system injury, such method comprising administering to said subject a composition comprising activated synthetic, light-emitting, water-soluble nanoparticles,
wherein, synthetic, light-emitting, water-soluble nanoparticles are activated prior to administration to create said activated synthetic, light-emitting, water-soluble nanoparticles; and
wherein said activated synthetic, light-emitting, water-soluble nanoparticles emit light in the infra-red or near infra-red spectrum.
6. The method of claim 5 , where the disorder of the central nervous system is the result of an ischemic stroke.
7. The method of claim 5 , wherein the disorder of the central nervous system is the result of an impact to the head.
8. The method of claim 5 , wherein the nanoparticles are selected from the group consisting of quantum dots, silica nanoparticles, magnetic iron oxide “nanoworms,” Cr3+/Pr3+ co-doped zinc gallogermanate, and gold nanoparticles.
