Biomimetic TME‐Responsive Nanotheranostics for Precise NIR‐II Ratiometric Photoacoustic Imaging and Synergistic Immuno‐Photothermal Therapy

Small, EarlyView.
A biomimetic Au/Ag@HMON‐NLG@CCM nanotheranostic is engineered for tumor microenvironment‐responsive NIR‐II ratiometric photoacoustic imaging and immune‐photothermal therapy. The integration of hyperthermia‐triggered immunogenic cell death with IDO‐blockade‐mediated metabolic remodeling promotes dendritic cell maturation and T‐cell activation.

Carbon monoxide‐triggered near‐infrared photoacoustic‐fluorescent integrated visualization tool for auxiliary diagnosis of heart failure and evaluation of reversal drug efficacy

Smart Molecules, EarlyView.
An activatable metal‐free probe CS‐CO enables the first non‐invasive photoacoustic/fluorescence visualization of carbon monoxide (CO) fluctuations during heart failure and its reversal, linking CO levels directly to disease status. Abstract Heart failure (HF), a major global health challenge with high morbidity and mortality, lacks effective biomarkers

From Cold to Hot: Nanozyme‐Based Strategies for Reprogramming the Tumour Immunoenvironment

Cell Proliferation, EarlyView.
Nanozymes, with multi‐enzyme catalytic activities, reprogram the immunosuppressive tumour microenvironment by inducing immunogenic cell death, relieving hypoxia, and depleting antioxidants, effectively converting immunologically “cold” tumours into “hot” ones to boost cancer immunotherapy efficacy.
