摘要：
3D DNA origami structures are employed to template 1.4 nm gold clusters into desired shapes. The gold clusters are further enlarged with gold ions from solution to form continuously metallized nanoparticles with controllable shapes and dimensions and narrow size distributions. This site-directed metallization constitutes a general and easy route to generate nanodonuts, nanorods, nanocuboids, and more complex structures with high yield and fidelity. © 2011 WILEY-VCH Verlag GmbH & Co.
