Abstract

A study designed to enhance the efficiency of self-assembly in nanoparticle-DNA systems through tailoring of oligonucleotide structure is discussed. A set of 10-nm gold nanoparticles modified with complimentary 30- base oligonucleotides building blocks was used as a model system. The assembly progression and nanostructure growth was characterized in-situ by monitoring the characteristic surface plasmon resonance band of gold nanoparticles with uv-visible spectrophotometry. The assembly kinetics and nanostructure growth were enhanced by modifying the surface bound oligonucleotide via partial duplex formation and DNA tailoring. The observed effect is attributed to the increased persistence length of the surface bound oligonucleotide, which reduces steric limitations due to coiling and base pair coordination to the gold interface.
