Bioactive Conductive Ti3C2Tx‐Ce Hydrogel Facilitates Spinal Cord Injury Repair Through ROS Scavenging and Mitochondrial Regulation

Advanced Functional Materials, EarlyView.
Bioactive conductive Ti3C2Tx‐Ce hydrogels with with scavenging ROS and alleviating neuronal mitochondrial dysfunction are exploited for SCI treatment. This functionality is attributed to interfacial activation modification of Ti3C2Tx with Ce3+ ions to in‐situ form Ce(OH)x‐mediated protective layer, which is beneficial to enabling stable intracellular ...

PROBLEMS OF IODIDE IONS DETERMINATION IN MULTIVITAMINS BY INDUCTIVELY COUPLED PLASMA ATOMIC-EMISSION SPECTROMETRY

Регуляторные исследования и экспертиза лекарственных средств, 2018
The article looks into the main problems of determination of iodine trace amounts in multivitamins by inductively coupled plasma-atomic emission spectrometry (ICP-AES), i.e. spectral overlaps attributable to macro-components, and the background effect of

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

Advanced 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

Advanced 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

Advanced 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.

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

Advanced 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.

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

Advanced 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
