Planet-satellite-type supracolloidal clusters represent a comparably young class of nanomaterials, which are unique with regard to structural order. In this prospective article, different approaches for their synthesis are discussed and compared. These synthetic methods enable the engineering of supracolloidal structural and adaptive properties, which in turn enables different emerging applications, such as in sensing and catalysis. These possibilities are explored on the basis of selected recent examples. A perspective about possible future developments is given at the end of this article.
