title: A template-free nano-wrapping technique for the fabrication of copper hollow nanospheres smaller than 20 nm.
abstract: A new template-free "nano-wrapping" method has been developed for the fabrication of copper hollow nanospheres with the smallest size of around 15 nm and its significance is highlighted to its composition tunability of the metal encapsulated inside the copper nanoshell.
