The nature of the constituent NPs (size and shape) within these assemblies dictates their optical properties. However, the construction of helical NP superstructures consisting of various anisotropic NPs remains challenging. Here, a set of cetyltrimethylammonium bromide derivatives is employed to transform constituent spherical gold NPs (\u22483 nm) within a chiral single\u2010helical assembly into gold nanoprisms (edge length \u2245 10 nm). Careful optimization of this strategy may lead to designed chiral NP architectures with tunable optical properties.<\/p>\n<p>\u87ba\u65cb\u7eb3\u7c73\u7c92\u5b50\uff08NP\uff09\u8d85\u7ed3\u6784\u662f\u4e00\u7c7b\u91cd\u8981\u7684\u624b\u6027NP\u7ec4\u4ef6\u3002 \u8fd9\u4e9b\u7ec4\u4ef6\u4e2d\u7ec4\u5206NP\uff08\u5c3a\u5bf8\u548c\u5f62\u72b6\uff09\u7684\u6027\u8d28\u51b3\u5b9a\u4e86\u5b83\u4eec\u7684\u5149\u5b66\u6027\u8d28\u3002 \u7136\u800c\uff0c\u7531\u5404\u79cd\u5404\u5411\u5f02\u6027NP\u7ec4\u6210\u7684\u87ba\u65cbNP\u8d85\u7ed3\u6784\u7684\u6784\u9020\u4ecd\u7136\u5177\u6709\u6311\u6218\u6027\u3002 \u8fd9\u91cc\uff0c\u4f7f\u7528\u4e00\u7ec4\u5341\u516d\u70f7\u57fa\u4e09\u7532\u57fa\u6eb4\u5316\u94f5\u884d\u751f\u7269\u5c06\u624b\u6027\u5355\u87ba\u65cb\u7ec4\u4ef6\u5185\u7684\u7ec4\u6210\u7403\u5f62\u91d1\u7eb3\u7c73\u9897\u7c92\uff08\u22483nm\uff09\u8f6c\u53d8\u6210\u91d1\u7eb3\u7c73\u68f1\u67f1\uff08\u8fb9\u957f\u224510nm\uff09\u3002 \u4ed4\u7ec6\u4f18\u5316\u8be5\u7b56\u7565\u53ef\u80fd\u4f1a\u5bfc\u81f4\u8bbe\u8ba1\u5177\u6709\u53ef\u8c03\u5149\u5b66\u7279\u6027\u7684\u624b\u6027NP\u7ed3\u6784\u3002<\/p>\n<p><a href=\"https:\/\/www.bihec.com\/olisclarity\/olis-dsm-172-cd-%e5%9c%86%e5%81%8f%e6%8c%af%e5%8f%91%e5%85%89%e5%85%89%e8%b0%b1%e4%bb%aa\/\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-57\" src=\"https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1.jpg\" alt=\"\" width=\"4256\" height=\"2832\" srcset=\"https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1.jpg 4256w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-300x200.jpg 300w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-768x511.jpg 768w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-1024x681.jpg 1024w, https:\/\/www.bihec.com\/olisclarity\/wp-content\/uploads\/sites\/7\/2018\/07\/DSM-172-2-1-272x182.jpg 272w\" sizes=\"(max-width: 4256px) 100vw, 4256px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<br><div class=\"tagcloud\"><\/div>","protected":false},"excerpt":{"rendered":"<p>\u5728\u87ba\u65cb\u91d1\u7eb3\u7c73\u9897\u7c92\u8d85\u6784\u4f53\u4e2d\u6784\u9020\u5404\u5411\u5f02\u6027 Deliberate Introduction of Particle Anisotropy in Helical Gold Nanopart <\/p>\n","protected":false},"author":1,"featured_media":13787,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_vp_format_video_url":"","_vp_image_focal_point":[]},"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13785"}],"collection":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/comments?post=13785"}],"version-history":[{"count":1,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13785\/revisions"}],"predecessor-version":[{"id":13789,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/posts\/13785\/revisions\/13789"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media\/13787"}],"wp:attachment":[{"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/media?parent=13785"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/categories?post=13785"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bihec.com\/olisclarity\/wp-json\/wp\/v2\/tags?post=13785"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
