In this minireview, we summarize current research dealing with the combination of noble‐metal nanoparticles and different families of supramolecular macrocycles (cyclodextrins, cucurbitnurils, calixarenes, and pillarnarenes). We intended to select relevant publications on the synthesis of noble‐metal nanoparticles with macrocycles acting as capping agents or/and reducing agents, as well as on the post‐synthetic metal‐nanoparticle modification with macrocycles. We also discuss strategies in which supramolecular chemistry is applied to direct the self‐assembly of nanoparticles and formation of polymer composites. We finally describe the main applications of these materials in various fields. Nanoparticles and macrocycles: Recent literature regarding the combination of supramolecular macrocycles and metal nanoparticles is reviewed, with particular emphasis on the synthesis, surface modification and assembly, as well as the potential applications of the obtained nanocomposites (SERS = surface‐enhanced Raman spectroscopy).
