Abstract
Provided herein are metal nanoparticles, metal nanopowders, methods of synthesizing the same, and radiation shields using the same.
Claims62
A metal nanoparticle comprising a metal core and an outer layer encompassing said core, said outer layer comprising a plurality of organic substituents bonded to said metal core, wherein said metal nanoparticle is less than 1 μm in length in all dimensions.
A radiation shield comprising a metal nanoparticle, said metal nanoparticle comprising a metal core and an outer layer encompassing said core, said outer layer comprising a plurality of organic substituents covalently bonded to said metal core, wherein said metal nanoparticle is less than 1 μm in length in all dimensions.
A method of making a plurality of metal nanoparticles, said method comprising:
- (a) contacting a metal with a diazonium compound substituted with an organic substituent;
- and
- (b) allowing the metal to react with the diazonium compound thereby forming a metal nanoparticle wherein said metal nanoparticle comprises a metal core and an outer layer encompassing said core, said outer layer comprising a plurality of said organic substituents covalently bonded to said metal core, wherein at least 50% of said plurality of metal nanoparticles are less than 1 μm in length in all dimensions.
