The Front Cover shows an overlay of an image of a metal nanoparticle network (blue) and sets of non‐spherical metal nanoparticles of different shapes (yellow). Beside networks, ellipsoidal, dumbbell‐like, astragal‐like and branched particles are formed. The character of these particles can be controlled by modulating particle/particle interaction by concentration of ligands and reducing agents during the reductive deposition of silver on preformed gold nanoparticles. An electrochemical open‐circuit mixed electrode concept is used for explaining the behavior of nanoparticles during metal deposition, particle assembling and particle growth. The particles are of interest for so‐called plasmonic labelling, nanoparticle‐based SERS‐sensing and heterogeneous catalysis. More information can be found in the Full Paper by J. M. Köhler et al. on page 1369 in Issue 12, 2019 (DOI: 10.1002/open.201900231).

封面：通过金/银纳米粒子的电势可控原位组装形成的金属纳米网络（ChemistryOpen 12/2019）

封面显示了金属纳米粒子网络（蓝色）和不同形状的非球形金属纳米粒子（黄色）的图像的叠加。在网络旁边，形成了椭圆形，哑铃状，黄芪状和分支状的粒子。这些颗粒的特性可以通过在预形成的金纳米颗粒上还原还原沉积银期间调节配体和还原剂的浓度来调节颗粒之间的相互作用来控制。电化学开路混合电极概念可用于解释纳米粒子在金属沉积，粒子组装和粒子生长过程中的行为。这些颗粒对于所谓的等离子体标记，基于纳米颗粒的SERS传感和非均相催化很重要。可以在J. M.Köhler等人的论文全文中找到更多信息。在2019年第12期中的第1369页（DOI：10.1002 / open.201900231）。
