Synthesis and Self-Assembly Behavior of Charged Au Nanocrystals in Aqueous Solution

Chem. Mater., 2015, 27 (12), pp 4431–4440 A series of water-soluble Au nanocrystals with different core sizes coated by either negatively or positively charged ligands are synthesized. We find a ligand interexchange process takes place when positively and negatively charged nanocrystals are mixed together and heated, resulting in mixed charged zwitterionic nanocrystals. The ligand exchange [...]

Amphiphilic DNA-dendron hybrid: a new building block for functional assemblies

Liying Wang,   Yu Feng,   Yawei Sun,   Zhibo Li,  Zhongqiang Yang,   Yan-Mei He,   Qing-Hua Fan and  Dongsheng Liu Soft Matter, 2011,7, 7187-7190 A new kind of amphiphilic DNA-dendron hybrid consisting of a highly hydrophobic dendron and a single stranded DNA is synthesized. The hybrid could assemble into long nanofibers in aqueous phase. The hybridization property of DNA at the shell of fibers associated [...]
