In article number 2008554, Davide Bonifazi, Stefano Casalini, Paolo Samorì, and co‐workers devise chemiresistors (CRs) based on 3D networks of Au nano‐ particles (AuNPs) covalently bridged by crown ether‐derivative supramolecular receptors for highly selective K + sensing. Real‐time, sensitive, fast, and stable chemic al sensing is achieved with a simple device technology. Such supramolecular CRs pave the way for future applications as point‐of‐care sensors for health monitoring.
