Shape-anisotropic particles and tunable "colloidal molecules" (A10)

合成和研究了由纳米颗粒组装成具有限定几何形状的稳定簇和等离子体纳米颗粒簇而产生的“胶体分子”。一个中心目标是调节胶体分子的大小和功能，并使它们具有柔性，其中颗粒之间的可切换距离由软颗粒或凝胶连接体提供，以模仿分子柔性。这为定制胶体开辟了前景，不仅具有复杂的几何形状，而且具有可调的全局尺寸和物理性质。

"Colloidal molecules" resulting from the assembly of nanoparticles into stable clusters with defined geometry and plasmonic nanoparticle clusters are synthesised and investigated. A central objective is to tune the size and function of the colloidal molecules and to make them flexible with switchable distances between the particles provided by soft particles or gel linkers, in imitation of molecular flexibility. This opens up perspectives for tailor-made colloids not only with complex geometries but also tunable global dimensions and physical properties.
