Engineered Nanoplatforms Targeting Activated Hepatic Stellate Cells for Liver Fibrosis Therapy via TGF‐β Axis Inhibition and Ferroptosis Induction

open access: yesAdvanced Healthcare Materials, EarlyView.
FeS‐VA@lanifibranor (FVL), an activated hepatic stellate cell (aHSC)‐targeted nanoplatform comprising vitamin A‐functionalized two‐dimensional iron sulfide nanosheets and lanifibranor, is engineered for precision therapy of liver fibrosis. FVL suppresses the TGF‐β signaling pathway by inhibiting SMAD2/3 phosphorylation and induces ferroptosis in aHSCs,

2‐Deoxyglucose Dendrimer‐Enabled Niclosamide Delivery to FRβ‐Expressing Macrophages Alleviates Endometriosis Progression and Associated Hyperalgesia

open access: yesAdvanced Healthcare Materials, EarlyView.
A folic acid (FA)‐conjugated 2‐deoxyglucose dendrimer selectively targets FRβ+ macrophages in endometriotic lesions, enabling precise intracellular delivery of niclosamide. This nonhormonal nanomedicine enhances drug solubility, provides controlled intracellular release, suppresses lesion growth, reduces inflammation and pain, and establishes FRβ ...

Hydrophilic Polymers Enable Gastrointestinal Transit Monitoring by Fluorine‐19 Magnetic Resonance Imaging

open access: yesAdvanced Healthcare Materials, EarlyView.
Hydrophilic fluorinated copolymers dissolve in chyme and give a strong, single 19F signal, unlike phase‐separating perfluorocarbons. Combined 1H‐19F MRI tracks their whole‐gut transit non‐invasively and without ionizing radiation. In rats, the tracers move through the gastrointestinal tract, resist resorption, and are well tolerated, a proof‐of‐concept

Zwitterionic Polymer Coating Enabled Chronic Dopamine Sensing and Electrophysiology Recording in Free‐Moving Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
Application of a zwitterionic poly(sulfobetaine methacrylate) (PSB) coating to microelectrode arrays and Ag/AgCl reference electrodes effectively inhibits biofouling and structural degradation. This strategy successfully enables simultaneous, long‐term electrophysiological recording and dopamine sensing in freely behaving mice, facilitating ...
