Quantum dot nanoarrays: self-assembly with single-particle control and resolution.

The develpoment of a highly selective immobilization strategy for the self-assembly of quantum dots (QDs) from solution on lithographically defined, biochemically functionalized metal nanopatterns is presented. Nanosale control is achieved for the formation of predominantly single-particle structures consisting of a QD coupled to a metal nanoparticle, and assembled into an ordered nanoarray.
