DNA-Templated Formation of Needle-like CdS Nanoparticles in Langmuir-Blodgett Film

Abstract Monolayer film of octadecylamine (ODA) and DNA-Cd2+ complex was co-transferred onto substrates by Langmuir-Blodgett (LB) technique. Needle-like CdS nanoparticles were formed by exposing the LB film to H2S. It is shown that DNA template plays important role in directing the formation of the needle-like CdS nanoparticles.
