In this work, we developed 3D ionic liquid (IL) functionalized graphene assemblies (GAs) decorated by ultrafine RuCu alloy nanoparticles (RuCu-ANPs) via a one-step synthesis process, and integrated it into microfluidic sensor chip for in situ electrochemical detection of NO released from living cells. Our findings have demonstrated that RuCu-ANPs on IL-GA exhibit high density, uniform distribution, lattice-shaped arrangement atoms, extremely size, possess electrocatalytic activity to oxidation the electrode. Meanwhile, with hierarchical porous structures can facilitate efficient electron/mass transfer at electrode/electrolyte interface cell culture. Moreover, graft IL molecules GA endows hydrophilicity facile well-controllable printing Consequently, resultant excellent sensing performances including fast response time, sensitivity, good anti-interference ability, reproducibility, long-term stability, as well biocompatibility, which be used an on-chip system culture real-time cells accurate stable characteristics physiological conditions.
