This article is published with open access at Abstract Herein we firstly reported a simple environment-friendly controllable synthetic method of CuSe nanosnakes at room temperature using copper salts and sodium selenosulfate as the reactants and bovine serum albumin BSA as foaming agent. As the amounts of selenide ions Se2- released from Na2SeSO3 in the solution increased the cubic and snake-like CuSe nanostructures were formed gradually the cubic nanostructures were captured by the CuSe nanosnakes the CuSe nanosnakes grew wider and longer as the reaction time increased. Finally the cubic CuSe nanostructures were completely replaced by BSA-CuSe nanosnakes. The prepared BSA-CuSe nanosnakes exhibited enhanced biocompatibility than the CuSe nanocrystals which highly suggest that as-prepared BSA-CuSe nanosnakes have great potentials in applications such as biomedical engineering.
