Structure determination by transmission electron microscopy has revealed the long sought 144-gold atom particle. The structure exhibits deviations from face-centered cubic packing of the gold atoms, similar to the solution structure of another gold nanoparticle, and in contrast to a previous X-ray crystal structure. Evidence from analytical methods points to a low number of 3-mercaptobenzoic acid ligands covering the surface of the particle.
透射电子显微镜的结构测定揭示了长期以来备受期待的 144 金原子粒子。该结构表现出与金原子面心立方堆积的偏离，类似于另一种金纳米粒子的溶液结构，与之前的 X 射线晶体结构形成对比。来自分析方法的证据表明，只有少量的 3-巯基苯甲酸配体覆盖在粒子表面。
