Mechanically and Chemically Defined PEG Hydrogels Improve Reproducibility in Human Cardioid Development

Advanced Healthcare Materials, EarlyView.
Synthetic matrix metalloproteinase (MMP)‐degradable polyethylene glycol (PEG)‐based hydrogels are developed to investigate the influence of mechanical and biochemical cues on cardioid development. Matrix stiffness and cell adhesion motifs significantly regulate cardioid formation, chamber morphogenesis, contractile function, and cardioid transcriptome.

Cholesterol Functionalized Nanoparticles Are Effective against Helicobacter pylori, the Gastric Bug: A Proof‐of‐Concept Study

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
Helicobacter pylori gastric infection is widespread and recurrency is common, fuelled by bacterial resistance to antibiotics. Therefore, specific and noninducing resistance alternative treatments are an urgent need. Taking advantage of this gastric pathogen auxotrophy for cholesterol, a “trojan horse” strategy for H.

3D Microtumors Representing Ovarian Cancer Minimal Residual Disease Respond to the Fatty Acid Oxidation Inhibitor Perhexiline

Advanced Healthcare Materials, EarlyView.
Minimal residual disease (MRD) leads to cancer relapse and poor survival in ovarian cancer. The lack of representative 3D models limits therapy development. The microfluidics‐based high throughput 3D microtumor platform described here generates clinically‐relevant MRD models. The 3D microtumors recapitulate the molecular signatures of MRD from patients.

Hollow‐Structured Nanorobot with Excellent Magnetic Propulsion for Catalytic Pollutant Degradation, Anti‐Bacterial and Biofilm Removal

Advanced Healthcare Materials, EarlyView.
A hollow‐structured Fe3O4@AgAu@PDA‐ZnPc nanosphere has been developed, exhibiting controllable catalytic activity and “photothermal‐photodynamic‐Ag+” coupling antibacterial characteristics. When subjected to a rotating magnetic field, these performances are uniquely enhanced by magnetic propulsion, allowing the nanosphere to function as a magnetic ...

Co‐Delivery of Multiple Toll‐Like Receptor Agonists and Avian Influenza Hemagglutinin on Protein Nanoparticles Enhances Vaccine Immunogenicity and Efficacy

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
This research highlights a novel application of protein nanoparticles to effectively modulate the strength, breadth, and bias of an immune response against influenza virus. Nanoparticles precisely co‐delivering antigen (H5) and multiple adjuvants (CpG and FliCc) present a way to improve and direct prophylactic immune responses which can be applicable ...

Novel Protein‐Rich Bioactive Bioink Stimulates Cellular Proliferation and Response in 3D Bioprinted Volumetric Constructs

Advanced Healthcare Materials, Volume 14, Issue 10, April 15, 2025.
This work describes a protein‐rich, low‐cost, bioactive bioink, prepared by adding eggwhite powder to functionalize an established alginate‐methylcellulose hydrogel blend and enhance its cellular response. The bioink not only maintains favorable printability and high shape fidelity but also exhibits remarkable bioactivity, thereby improving the ...

Active Iron‐Drug Nanocomplexes Improve Photodynamic and Photothermal Cancer Therapy by Mitigating Tumor Hypoxia and Counteracting Tumor Heat Resistance

Advanced Healthcare Materials, Volume 14, Issue 9, April 4, 2025.
A pH‐responsive nanocomplex (PAFH) enhances photodynamic (PDT) and photothermal therapy (PTT) by addressing tumor hypoxia and heat resistance. Under laser irradiation, PAFH releases hypericin for singlet oxygen generation and apigenin to inhibit HSP‐90 and alleviate hypoxia.

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

Advanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.

HGF/c‐Met Axis‐Targeted Nanotherapy via GSH‐Responsive Polymer Platforms Suppresses Uveal Melanoma Metastasis

Advanced Healthcare Materials, EarlyView.
To suppress uveal melanoma metastasis (UM), the GSH‐responsive polymer named NP@Oxa/Criz has been successfully prepared. NP@Oxa/Criz selectively accumulates in UM tumors, targeting HGF/c‐Met Axis to undermine the stemness and metastasis of UM while triggering immunogenic cell death through DAMPs release to boost anti‐tumor immunity.
