Resumen: Glucose and glutathione (GSH) are key biomolecules for the regulation and growth of tumor cells. The use of inorganic nanocatalysts in biomedicine to target and deplete such specific molecules represents a novel and promising strategy against cancer. In this work, we present a ternary assembled nanohybrid based on Au and CuFe2O4 with the capability to simultaneously deplete glucose and GSH and generate reactive oxidative species (ROS) in a cascade process. We describe an example of a synergistic heterogeneous nanoarchitecture able to maintain the glucose oxidase-like activity of Au while preventing its deactivation in the presence of GSH. Au sites remain active due to the rapid response of the Cu–Fe co-catalyst to deplete GSH levels. This example of hybrid heterostructure represents an appealing alternative with dual-activity within the tumor microenvironment (TME) for potential anticancer therapy.
