A facile method towards cyclic assembly of gold nanoparticles using DNA template alone

Abstract

We report on a novel facile method towards a synthesis of cyclic assembled gold nanoparticles (AuNPs) by mixing each of the DNA-monoconjugated AuNPs, i.e., “DNA building blocks” for cyclic assembly, and UV-induced interstrand crosslinking. By using our designed template DNA for cyclic assembly which possesses complementary sequences for cyclic assembly of the AuNPs, we demonstrated the formation of the cyclic assembly of AuNPs, i.e., triangular and square assemblies of AuNPs, which were confirmed by TEM analysis.
