Tumor microenvironment responsive and nanozyme‐catalyzed photodynamic therapy via lysosome‐localized copper‐doped carbon dots

Responsive Materials, EarlyView.
The lysosome‐localized copper‐doped carbon dots (Cu‐MLCDs) leverage the high expression of glutathione (GSH)/H2O2 in the tumor microenvironment to achieve fluorescence reactivation enhancement. Through its multi‐nanozyme activities (glutathione peroxidase, peroxidase, and catalase), this nanoplatform relieves hypoxia, depletes GSH, and synergistically ...

Quantitative Imaging of Human Hemoglobin Binding to Staphylococcus aureus With Single‐Molecule Resolution

Small, EarlyView.
Single‐molecule localization microscopy is exploited to quantify the number of hemoglobin copies bound to specific receptors on S. aureus wall. This quantification supports the design of a photoactive derivative of hemoglobin able to photo‐inactivate S.

Hematoporphyrin derivative-mediated photodynamic techniques for the diagnosis and treatment of chordoma

Photodiagnosis and Photodynamic Therapy
Background: Chordoma is a rare congenital low-grade malignant tumor characterized by infiltrative growth. It often tends to compress important intracranial nerves and blood vessels, making its surgical treatment extremely difficult. Besides, the efficacy

Advances in the application of photodynamic diagnosis in Skin Tumors

Photodiagnosis and Photodynamic Therapy
Photodynamic Diagnosis (PDD) is a non-invasive imaging technique. It relies on a photosensitizer that, when activated by a specific light source, causes metabolically active tissues like tumors to emit visible red fluorescence. PDD offers high sensitivity, high specificity, and real-time visualization.

Driving Drugs Deeper: Force‐Driven Microneedle Systems for Active Therapy and Their Road Towards Clinical Implementation

Small, EarlyView.
Force‐driven microneedles are presented as active therapeutic microdevices that overcome the diffusion limits of conventional patches. By integrating gas generation, magnetic actuation, cavitation, or iontophoresis, these systems drive payloads deeper into tissue, enabling faster, more controlled delivery and highlighting key design principles and ...

HER2‐Targeted AIE Nanotheranostics Overcome SHR‐A1811 Resistance via Immunogenic Pyroptosis and Tumor‐Associated Macrophage Reprogramming in Breast Cancer

Small, EarlyView.
HER2‐targeted AIE780‐A1811 nanoparticles self‐assemble via amide coupling of a mitochondria‐directed photosensitizer with the ADC SHR‐A1811. Upon 660 nm irradiation, they generate ROS, photothermal effects, and controlled drug release, inducing immunogenic pyroptosis and M2‐to‐M1 macrophage reprogramming. This dual action remodels the immunosuppressive
