Ordered Arrays of Raman Nanosensors for Ultrasensitive and Location Predictable Biochemical Detection
摘要：Surface-enhanced raman scattering (SERS) effect is sensitive enough for single-molecule biochemical detection, but it is extremely difficult to obtain a large number of SERS hotspots for sensitive and reproducible detection. It is even more challenging to assemble the hot-spots at designated positions for location predictable sensing. On page 5457, D. L. Fan and co-workers report an original strategy for the synthesis, manipulation, and assembling of plasmonic nanocapsule SERS sensors for high-sensitivity biochemical detection at predictable locations.
图评：艺术品与材质一直有着分不开的关系，恰如其分的设计需要基于恰如其分的材质。这张设计虽然是平面的图像，但是看到这张图像会让人忘记了平面的构图和色彩，念念不忘印象深刻的是画面中那触手可及的质感，犹如一件精美的饰品忍不住想伸手触摸。回到封面设计角度来说，材质的美感是设计美感中的重要构成部分，因此如果挖空心思也想不到文章中的物质或者结构如何表现的时候也许可以从质感方向来寻找灵感。
