title: Controlling an electrostatic repulsion by oppositely charged surfactants towards positively charged fluorescent gold nanoclusters.
abstract: A novel positively charged fluorescent gold nanocluster was successfully synthesized using the shortest cationic thiol, thiocholine. Effective control of electrostatic repulsion by the introduction of an anionic surfactant afforded a nanocluster that showed blue fluorescence emission.
