In article number 1803518 , Helmut Cölfen and co‐workers use analytical ultracentrifugation to fabricate tailored nanoparticle gradient materials. Gradients of gold spheres, gold rods, and spherical iron oxide nanoparticles are generated by sedimentation of the nanoparticles in a thermoreversible gelatin matrix. The materials can be simulated in advance and the gradients are detected online by the optical systems of the centrifuge to produce desired property gradients.
