Contribution of nanoscale curvature to number density of immobilized DNA on gold nanoparticles.

Abstract

We report the curvature size dependence of the density of attached single-stranded DNA (ssDNA) on the surface of gold nanoparticles. The densities of immobilized ssDNA on 10, 20, 30, and 50 nm gold nanoparticles were examined, and we found that the maximum density of the immobilized ssDNA on 10 nm particles was 13 times larger than that on 50 nm particles, which was still 10 times larger than that on flat gold surfaces. This result indicates the importance of curvature in the nanometer-scale attachment of ssDNAs to nanoparticles.
