Abstract Cancer remains a global health challenge necessitating innovative therapies. We introduce a strategy to disrupt cancer cell redox balance using gold nanoparticles (Au NPs) as electron sinks combined with electroactive membranes. Utilizing Shewanella oneidensis MR-1 membrane proteins, we develop liposomes enriched with c-type cytochromes. These, coupled with Au NPs, facilitate autonomous electron transfer from cancer cells, disrupting redox processes and inducing cell death.

Catalytic nanoparticles (CNPs) as heterogeneous catalyst reveals superior activity due to their physio-chemical features, such as high surface-to-volume ratio and unique optical, electric, and magnetic properties. The CNPs, based on their physio-chemical nature, can either increase the reactive oxygen species (ROS) level for tumor and antibacterial therapy or eliminate the ROS for cytoprotection, anti-inflammation, and anti-aging.
