Anisotropic Gold Nanoparticles: Synthesis, Properties, Applications, and Toxicity Na Li, Pengxiang Zhao,* and Didier Astruc* ISM, UMR CNRS 5255, Univ. Bordeaux 33405 Talence Cedex (France) E-mail: d.astruc@ism.u-bordeaux1.fr Dr. P. Zhao Science and Technology on Surface Physics and Chemistry Laboratory P.O. Box 718-35, Mianyang 621907, Sichuan (China) E-mail: zhaopengxiang831015@126.com A nisotropic gold nanoparticles (AuNPs) have attracted the interest of scientists for over a century, but research in this field has considerably accelerated since 2000 with the synthesis of numerous 1D, 2D, and 3D shapes as well as hollow AuNP structures. The anisotropy of these nonspherical, hollow, and nanoshell AuNP structures is the source of the plasmon absorption in the visible region as well as in the near-infrared (NIR) region. This NIR absorption is especially sensitive to the AuNP shape and medium and can be shifted towards the part of the NIR region in which living tissue shows minimum absorption. This has led to crucial applications in medical diagnostics and therapy (“theranostics”), especially with Au nanoshells, nanorods, hollow nanospheres, and nanocubes. In addition, Au nanowires (AuNWs) can be synthesized with longitudinal dimensions of several tens of micrometers and can serve as plasmon waveguides for sophisticated optical devices. The application of anisotropic AuNPs has rapidly spread to optical, biomedical, and catalytic areas. In this Review, a brief historical survey is given, followed by a summary of the synthetic modes, variety of shapes, applications, and toxicity issues of this fast-growing class of nanomaterials.请小伙伴们下载后给个好评！    |
