Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

open access: yesAdvanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.

Application and Single‐Cell Regulation Mechanism of Engineered EVs Combined With 4D‐Printed Hydrogel for Infected Burn Repair

open access: yesAdvanced Science, EarlyView.
4D bioprinted hydrogel loaded with FGF2‐modified extracellular vesicles (4D@F‐EVs) targets dermal fibroblasts and elevates local wound FGF2 levels via sustained release of F‐EVs. It activates PI3K‐Akt signaling, restores critical KGF+ fibroblast–KGFR+ keratinocyte crosstalk, enhances robust angiogenesis and collagen deposition to efficiently repair ...

Hydraulic Pressure‐Programmed Molecular Transport in Tough Hydrogels

open access: yesAdvanced Science, EarlyView.
Hydraulic pressure is introduced as a programmable parameter for regulating molecular transport in tough hydrogel membranes. Reversing the pressure direction accelerates or slows transport, tuning characteristic transport times over a 65‐fold range while achieving molecular separation and controlled delivery.
