Enzyme-directed positioning of nanoparticles on large DNA templates.
A method to position nanoparticles onto DNA with high resolution using an enzyme-based approach is described. This provides a convenient route to assemble multiple nanoparticles (e.g., Au and CdSe) to specific positions with a high level of control and expandability to more complex assemblies. Atomic force microscopy is used to analyze the nanostructures, which have potential interest for biosensor, optical waveguide, molecular electronics, and energy transfer studies.
