DNA Nanotechnology: Overcoming the Coupling Dilemma in DNA‐Programmable Nanoparticle Assemblies by “Ag+ Soldering” (Small 19/2015)
Source abstract
Abstract
Strong interparticle coupling is important to facilitate charge and energy transfer. Despite great successes in DNA nanotechnology, the weak coupling of DNA-assembled nanoparticles is often overlooked. On page 2247, Z. Deng and co-workers describe DNA-programmable Ag+ soldering to address this challenge. Firstly, monovalent (with minimized steric effects) DNA-conjugated gold nanoparticles are assembled into desired structures (e.g., a dimer), and then Ag+ ions are introduced to solder nanoparticles positioned in close proximity to realize strong plasmon coupling.
