A Herbal‐Piezoelectric Heterojunction Strategy to Potentiate Bacterial Cuproptosis‐Like Death and Remodel the Inflammatory Microenvironment in Infection‐Associated Implant Osteomyelitis

Advanced Science, EarlyView.
A titanium implant coating integrating berberine and copper‐doped strontium titanate leverages ultrasound to compromise bacterial membranes and induce cuproptosis‐like death. This approach resolves S. aureus infections in osteomyelitis models while suppressing inflammation and promoting osseointegration, demonstrating a dual‐functional strategy against

Senescence‐Inducing Therapy Sequential NIR‐II Mild Photothermal/Senolytic Therapy of Triple Negative Breast Cancer

Advanced Science, EarlyView.
Targeting triple‐negative breast cancer remains challenging due to limited therapies and drug resistance. A sequential theranostic strategy combining palbociclib‐induced senescence (enhancing heat sensitivity via HSP70 downregulation) with an NIR‐II nanoplatform (IQ NPs) for mild photothermal therapy (PTT) and quercetin‐mediated senolysis is developed.

A “3+2” Cooperation Pattern of Amphipathic AIE Phototheranostic System for Multimodal Image‐Guided Synergistic Type I/II Photodynamic‐Photothermal Therapy

Advanced Science, EarlyView.
A “3+2” cooperation pattern of amphipathicity PTA (named TDTMSB) with aggregation‐induced emission (AIE) features is designed and synthesized to perform near‐infrared I/II fluorescence imaging, photoacoustic imaging, photothermal imaging, and Type I/II photodynamic therapy (PDT)‐photothermal therapy (PTT) synergistic phototherapy for malignant tumors ...

Silica-coated super paramagnetic iron oxide nanoparticles (SPION) as biocompatible contrast agent in biomedical photoacoustics

Biomedical Optics Express, 2012
In this study, we report for the first time the use of silica-coated superparamagnetic iron oxide nanoparticles (SPION) as contrast agents in biomedical photoacoustic imaging. Using frequency-domain photoacoustic correlation (the photoacoustic radar), we
