Interfacial Bioengineering of Dynamic Networks Hybrid Hydrogel for Programmed Intervention in Oral Precancerous Epithelial States

open access: yesAdvanced Healthcare Materials, EarlyView.
This study develops a dual‐bioinspired hydrogel, MSA@PGel (macrophage membrane‐coated and salvianolic acid B/5‐aminolevulinic acid co‐loaded liposomes embedded in a polydopamine‐based gel), that integrates macrophage membrane‐mediated active targeting and mussel‐inspired wet adhesion for programmed intervention in oral precancerous lesions.

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.

Ion‑Mediated Structural Engineering of Hydrogel Interfaces for Tunable Mechanical and Analyte Diffusion Properties in Electrochemical Biosensors

open access: yesAdvanced Materials, EarlyView.
An ion‐mediated structural engineering strategy enables versatile modulation of PVA–Alginate hydrogel microstructure. We systematically examine how different ion combinations affect hydrogel mechanical properties and analyte diffusivity. Applying this novel strategy to hydrogel as the outer membrane in an electrochemical glucose biosensor allows ...

Scalable Solar Evaporator Based on Bandgap Engineered CuMnCrO4 Spinel Oxide with Salt‐Resistant Property for Contaminated Seawater

open access: yesAdvanced Materials, EarlyView.
Incorporating multiple cations (Cu2⁺ and Cr3⁺) into the Mn3O4 spinel lattice strategically tunes the electronic structure, narrowing the bandgap from 2.3 to 1.49 eV. This enhances visible–NIR light absorption and photothermal conversion, enabling a high water evaporation rate of 4.1 kg m−2 h−1 under 1 sun.

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

open access: yesAdvanced Materials Interfaces, EarlyView.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.
