Non‐Enzymatic Destruction of the Extracellular Matrix for Activatable Orthotopic Tumor Treatment and Enhanced Drug Penetration

open access: yesAdvanced Functional Materials, EarlyView.
Supramolecular biomimetic nanoaggregates (HFCu NAs), constructed with fluorinated histidine and copper ions via metal coordination and aromatic packing, exhibit enhanced reactive oxygen species (ROS)generation at tumor sites, which results in stepwise collapse of the extracellular matrix (ECM), affording tumor microenvironment responsive “turn‐on” 19F ...

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation
