Carbon‐Based Flexible Electrode for Efficient Electrochemical Generation of Reactive Chlorine Species in Tumor Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A flexible electrode loaded with a carbon nanowire network (CC@C‐NWN) is developed for electrochemically generating reactive chlorine species (RCS) from abundant chloride ions in body fluids for tumor therapy. CC@C‐NWN enhances chlorine evolution, inducing redox dysregulation and synergistic apoptosis‐ferroptosis in tumor cells.
