Ferritin‐Doped Nanoparticles Triggered Tumor‐Specific Darkening for Enhanced Photothermal Tumor Ablation and Immune Activation

Advanced Healthcare Materials, EarlyView.
Ferritin‐doped hybrid nanoparticles triggered accurate tumor‐specific hemorrhage for enhanced in situ photothermal therapy and evoked anti‐tumor immunity. Notably, HFn/GA‐Fe specifically induced tumor hemorrhage 12 h after intravenous injection, resulting in visible color darkening. Through photoacoustic imaging, tumor vessels could be clearly observed

Thermo‐Fluorescent Bactericidal Quantum Dots Based Smart Multifunctional Textiles via Molecular Surface Engineering and 3D‐Printed Interlocked Architectures

Advanced Healthcare Materials, EarlyView.
A versatile approach is presented for fabricating smart multifunctional textiles by integrating thermo‐fluorescent carbon dot/polymer nanocomposite coatings with 3D‐printed interlocked architectures. The fabrics exhibit temperature‐responsive fluorescence, durable hydrophobicity, strong antibacterial and antioxidant activity, and enhanced UV protection.

Self‐Cooling Molecular Spin Qudits

Advanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
