Colloidal supraparticles promise exciting applications. But are they mechanically stable enough to deliver these promises? We investigate the mechanics of colloidal supraparticles under compression. We find a scaling relationship between the supraparticle geometry and its fracture, and how the fracture is influenced by interparticle adhesion. Many thanks for Benoit Merle, Prof. Peukert, Andi Ströbel, Jan Schwenger and the coauthors for the great collaboration!
