[资源] surface plasmon resonance技术表征单个纳米颗粒表面电催化反应

两篇关于plasmonic-based electrochemical current-imaging technique的文章。
一篇新闻报道，主题是A surface plasmon resonance imaging technique can be used to probe electrocatalytic reactions occurring on individual nanoparticles.
另一篇是与之相关的论文，摘要如下：
The electrocatalytic properties of nanoparticles depend on their size, shape and composition. These properties are typically probed by measuring the total electrocatalytic reaction current of a large number of nanoparticles, but this approach is time-consuming and can only measure the average catalytic activity of the nanoparticles under study. However, the identification of new catalysts requires the ability to rapidly measure the properties of nanoparticles synthesized under various conditions and, ideally, to measure the electrocatalytic activity of individual nanoparticles. Here, we show that a plasmonic-based electrochemical current-imaging technique can simultaneously image and quantify the electrocatalytic reactions of an array of 1.6E5 platinum nanoparticles printed on an electrode surface, which could
facilitate high-throughput screening of the catalytic activities of nanoparticles. We also show that the approach can be used to image the electrocatalytic reaction current and measure the cyclic voltammograms of single nanoparticles.
