One‐Step Preparation of Lanthanide‐Doped Polyurea Multicolor Microspheres for Versatile Fluorescent Applications

open access: yesAdvanced Science, EarlyView.
Lanthanide‐doped polyurea microspheres are prepared via a facile one‐step precipitation polymerization. They exhibit strong hydrogen‐bonding and coordination interactions with excellent properties, including multicolor emission, high quantum yield (75.3%), remarkable stability, redispersibility, and biocompatibility.

Hemoglobin's α‐Helix‐to‐β‐Sheet Transition Enables Targeted mRNA Delivery to the Lung

open access: yesAdvanced Science, EarlyView.
Acidic heating converts hemoglobin into β‐sheet‐rich fibrils with positively charged surfaces. These hemoglobin fibrils electrostatically complex IL‐11 scFv mRNA, selectively bind circulating platelets, and hitchhike to the lung, where they are enriched in fibroblasts.

Human Urine Stem Cells Alleviate Pulmonary Fibrosis via Inhibiting Macrophage‐Myofibroblast Transition

open access: yesAdvanced Science, EarlyView.
Therapeutic role and mechanism of human urine stem cells (hUSCs) in pulmonary fibrosis. hUSCs alleviated pulmonary fibrosis by selectively inhibiting macrophage‐myofibroblast transition (MMT) in two ways: on one hand, hUSCs inhibited mitochondrial reactive oxygen species (mtROS) production and apoptosis/senescence of epithelial cells in pulmonary ...

A Blood‐Derived Double‐Network Hydrogel with Robust Wet Adhesion for Keratinized Mucosa Regeneration via Neutrophil Phenotype Reprogramming and Mechanophysical Niche Modulation

open access: yesAdvanced Science, EarlyView.
The iPRF‐MA/Alg‐NHS/Lut@EGCG (PGAE) double‐network hydrogel achieves durable wet adhesion in the oral environment. It simultaneously reprograms neutrophils from NETosis to phagocytosis for biofilm clearance, and activates the FAK‐RhoA‐YAP mechanotransduction pathway in gingival fibroblasts to drive extracellular matrix remodeling, thereby promoting ...

Optical Windows for Transcranial Brain Imaging in Living Mice: Skull Thinning, Clearing, and Beyond

open access: yesAdvanced Science, EarlyView.
Longitudinal, noninvasive in vivo imaging is crucial for studying brain physiology. Advances in transcranial optical windows and multiphoton microscopy have improved imaging depth, but their performance often deteriorates over time. This work investigated various transcranial window approaches and found that skull regrowth limits image quality.
