title: A new strategy improves assembly efficiency of DNA mono-modified gold nanoparticles.
abstract: We report a new strategy to prepare DNA mono-modified gold nanoparticles (AuNPs). By adding a short rigid duplex proximal to the AuNPs, the assembly efficiency of DNA mono-modified AuNPs with Y-shaped DNA could be improved nearly 6-fold.
