Nucleotide-directed growth of semiconductor nanocrystals

J Am Chem Soc. 2006 Jan 11;128(1):64-5. doi: 10.1021/ja057002+.

Abstract

We engineer colloidal quantum dot nanocrystals through the choice of biomolecular ligands responsible for nanoparticle nucleation, growth, stabilization, and passivation. We systematically vary the presence of, and thereby elucidate the role of, phosphate groups and a multiplicity of functionalities on the mononucleotides used as ligands. The results provide the basis for synthesis of nanoparticles using precisely controlled synthetic oligonucleotide sequences.
