Abstract
The present invention includes a method for scavenging nitric oxide. The method includes contacting the nitric oxide with cerium oxide nanoparticles having a low 3+/4+ ratio.
Claims14
A method for scavenging nitric oxide comprising contacting the nitric oxide with ceria nanoparticles having a low 3+/4+ ratio.
7-11. (canceled)
A method for detecting an amount of nitric oxide in a sample comprising:
- contacting the sample with an effective amount of cerium oxide nanoparticles having a low 3+/4+ ratio;
- and
- detecting a change in oxidation state of the cerium oxide nanoparticles, the detection being indicative of the presence of nitric oxide in the sample.
A device for reducing an amount of nitric oxide within a nitric oxide-containing fluid stream comprising:
- a housing:
- a quantity of cerium oxide nanoparticles having a low 3+/4+ ratio disposed within the housing;
- an inlet configured for receiving the nitric-oxide containing fluid stream to be treated with the low ratio cerium oxide nanoparticles;
- and
- an outlet in the housing configured for allowing release of a fluid stream having a reduced amount of nitric oxide relative to the nitric-oxide containing fluid stream after contact with the low ratio cerium oxide nanoparticles.
