An Edible H2O2 Biosensor for Gastrointestinal Metabolites and Peroxidase Enzyme Quantification

Advanced Healthcare Materials, EarlyView.
We present an edible biosensor for gastric fluid analysis that integrates a caffeic acid–horseradish peroxidase redox system into an edible electrolyte‐gated transistor. The device enables rapid, low‐volume detection of H2O2 and, with minimal modification, metabolites and enzyme activity in simulated gastrointestinal conditions.

High‐Throughput Generation of Tumor Spheroids via Droplet Microfluidics for siRNA‐Loaded Nanomedicine Assessment

Advanced Healthcare Materials, EarlyView.
A droplet microfluidic platform is employed to enable high‐throughput, uniform tumor spheroid generation for evaluating siRNA‐loaded nanomedicines at the protein level. As a proof of concept, breast (MCF‐7) and brain (U87 MG) cancer cell lines are investigated using this platform, revealing penetration profiles and therapeutic responses between the two

Spatial Patterning of Modular Gelatin‐Peroxide Microspheres in Melt‐Electrowritten Scaffolds Provides Controlled Oxygen Generation and Mitigates Hypoxia and Cytotoxicity

Advanced Healthcare Materials, EarlyView.
A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...

Hybrid Nanofibers for Multimodal Accelerated Wound Healing

Advanced Healthcare Materials, EarlyView.
Fabrication of wound healing scaffolds based on biocompatible nanofibers. Nanofibers offering high surface area, flexibility, and biocompatibility significantly improved the healing outcome in vivo. Histological, immunological, and anti‐inflammatory markers are noticeably better in treated wounds.

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

Advanced 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.

Engineered ETS1‐Nanoconjugate Restores Immune Homeostasis through Dual Immune‐Vascular Modulation in Relapsing and Progressive Multiple Sclerosis

Advanced Healthcare Materials, EarlyView.
The biomimetic nanoplatform IMNP (ETS1 pDNA/PBAE@ITP‐MM) undergoes targeted disassembly at inflammatory vascular sites to release the ETS1 plasmid (pETS1). This release initiates a cascade of effects that inhibit pathogenic pathways and support immune homeostasis. (Abbreviations: EndMT, endothelial‐to‐mesenchymal transition; EC, endothelial cell; TC, T
