Coupling Reversible Clustering of DNA‐Coated Gold Nanoparticles with Chemothermal Cycloaddition Reaction

Abstract Stimuli‐responsive, optically‐active colloidal systems are convenient signal transducers capable of monitoring environmental changes at the nanoscale. We report on coupling chemo‐thermal cycloaddition reaction with temperature‐sensitive, DNA‐coated gold nanoparticles. found that concentration chemical fuel, dictating temperature mixture, is a primary ingredient in controlling extent reversible clustering Our results show rational and can open up new possibilities tracking change local using aggregation/redispersion
