摘要：

Specifically designed dimeric, planar trimeric, tetrameric, pentameric, and 3D hexameric assemblies of Au nanoparticles were constructed from self-assembling DNA modules that contain disulfide groups, for attachment to the nanoparticles, and covalently linked 2,5-bis(2-thienyl)pyrrole (SNS) monomers. Treatment of these arrays with horseradish peroxidase and H2O2 (HRP/H2O2) results in bond formation between the SNS monomers that cross-links or ligates the DNA modules making the assemblies permanent ("fixed").
