DNA templated fluorescent gold nanoclusters reduced by Good’s buffer: from blue emitting seeds to red and near infrared emitters
(NRC Research Press, 2015-01-22)DNA-templated fluorescent gold nanoclusters (AuNCs) have been recently prepared showing higher photostability than the silver counterpart. In this work, we examined the effect of pH, DNA length, DNA sequence, and reducing ... -
Light-Activated Metal-Coordinated Supramolecular Complexes with Charge-Directed Self-Assembly
(American Chemical Society, 2013-02-21)Metal-coordinated materials are attractive for many applications including catalysis, sensing, and controlled release. Adenine and its derivatives have been widely used to generate many coordination complexes, polymers, ... -
A platinum shell for ultraslow ligand exchange: unmodified DNA adsorbing more stably on platinum than thiol and dithiol on gold
(Royal Society of Chemistry, 2015-08-04)Due to the ultraslow ligand exchange rate on Pt, non-thiolated DNA is adsorbed on platinum nanoparticles (PtNPs) more stably than thiolated and even dithiolated DNA on AuNPs. Adsorption kinetics, capacity and stability are ...
