Abstract
The present communication demonstrates for the first time that carbon nanobelts (CNBs) were facilely synthesized on a large scale via pyrolysis of a 1,8-diaminonaphthalene (DAN)-NiCl2 center dot 6H(2)O mixture under Ar followed by acid leaching. We further demonstrate that such CNBs can be used as a novel effective fluorescent sensing platform for DNA. This sensing platform exhibits high selectivity and sensitivity with a detection limit of 5 nM.
