Engineering Hydrogen‐Down Water Configurations for Ampere‐Level Electrochemical CO2 Reduction to Formate

open access: yesAdvanced Functional Materials, EarlyView.
Electrochemical CO2 reduction (ECR) to formate is a promising route for sustainable chemical production. Herein, we report the synthesis catalysed byBi‐HfO2@C. The AIMD simulations, DFT calculations, and in situ SEIRAS measurements show that the modification of HfO2 on the Bi surface steers the interfacial water to adopt a favorable hydrogen‐down (OH2↓)

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

Doxorubicin‐Loaded Metal–Organic Framework for Ferroptosis‐Enhanced Chemotherapy Through Sustained Zn Release and Glutathione Peroxidase Downregulation

open access: yesAdvanced Healthcare Materials, EarlyView.
A robust zinc‐based metal–organic framework (ZnMOF) enables dual functions of doxorubicin delivery and sustained Zn2+ release to trigger ferroptosis‐enhnaced chemotherapy. DOX@ZnMOF effectively depletes intracellular glutathione, suppresses GPX4, and elevates reactive oxygen species, leading to efficient oxidative DNA damage and apoptosis.

Understanding the Effects of Conductive Polymer Electrode Coating on Recorded Neural Signals

open access: yesAdvanced Healthcare Materials, EarlyView.
Conductive polymer coatings are widely explored to improve the quality of signals recorded with chronically implanted neural electrodes, offering enhanced biocompatibility along with reduced electrode impedance. Combining computational modelling and data from PEDOT:PTS coated and PtIr electrodes in rats, we show that improvements in signal quality with

Nanobiosensor Based on Catalytic Palladium Nanoclusters and Oxidases for Bianalyte Electrochemical Determination: Glucose and Ethanol in Sweat

open access: yesAdvanced Healthcare Materials, EarlyView.
A nanobiosensor for fast and simultaneous determination of sweat glucose and ethanol is presented. Deposited oxidase enzymes consume oxygen in the presence of the substrates, and co‐deposited palladium nanoclusters catalyze the electrochemical oxygen reduction, basis of the detection.

Engineering Extracellular Vesicle Production Through Magnetic Ion Channel Activation for Bone Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Magnetic Ion Channel Activation (MICA) enables remote stimulation of mechanosensitive ion channels using functionalised magnetic nanoparticles, enhancing extracellular vesicle (EV) biogenesis is pre‐osteoblasts. MICA desrived EVs exhibit typical nano‐vesicular characteristics but display superior pro‐osteogeneic activity, promoting mesenchymal stem ...

Taming the Immiscibility of Gold, Iron, and Boron to Craft Chemodegradable Nanoparticles for Multimodal Imaging and Radiotherapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Over half of cancer patients undergo radiotherapy. Laser ablation enabled the synthesis of immiscible Au‐Fe‐B nanoparticles designed as degradable bimodal radiosensitizers for X‐ray radiotherapy (XRT), boron neutron capture therapy (BNCT), and bimodal imaging for X‐ray computed tomography (CT) and magnetic resonance imaging (MRI). These nanosensitizers

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

open access: yesAdvanced 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

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.
