Abstract
Disclosed herein are methods for forming one or more nanoparticles. The methods include depositing a solution comprising a block copolymer and a metal salt into one or more square pyramidal nanoholes formed in a substrate, and annealing the substrate to provide a single nanoparticle in each of the one or more square pyramidal nanoholes.
Claims20
A method of forming one or more nanoparticles, the method comprising:
- depositing a solution comprising a block copolymer and a metal salt into one or more square pyramidal nanoholes formed in a substrate;
- and,
- annealing the solution containing substrate under conditions to reduce the metal salt in the solution to a metal and form a single nanoparticle in of the one or more square pyramidal nanoholes,
- wherein the substrate has a solvent contact angle of about 20° to about 40°.
