英文摘要	National Natural Science Foundation of China [21036004, 20976146]; Research Fund for the Doctoral Program of Higher Education of China [20100121110032, 20110121120018]; Fujian Province Science & Technology Program of China [2010H6024]; Size- and shape-based separation is an effective complementary process to prepare well-defined materials for fundamental studies and applications. However, the separation of nanoparticles polydisperse in both shape and size remains a great challenge. A mixture of gold nanospheres and nanoplates with a wide standard deviation (SD) (21% for the former and 30% for the latter) were synthesized in the same batch using sun-dried Cacumen Platycladi leaf extract. Size-separation of Au nanoparticles was achieved via density gradient centrifugation and the subsequent shape separation was achieved via agarose gel electrophoresis. Transmission electron microscopy (TEM) revealed that, monodispersed nanospheres (SD: 4-5%) and nanoplates (SD: 6-7%) were obtained separately after the two-step separation below.
