In Situ Photo‑Crosslinked Functional Bilayer Hydrogel Modulates Local Microenvironment and Remyelination After Optic Nerve Injury

open access: yesAdvanced Science, EarlyView.
A blue‐light‐crosslinked bilayer hydrogel was developed for local optic nerve repair. The adhesive GM‐Odex outer layer seals and anchors the lesion, while the non‐adhesive GM‐imid inner layer releases MPDA‐Cle without obstructing CSF flow. This system modulates oxidative and inflammatory microenvironments, supports oligodendrocyte differentiation and ...

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides

open access: yesAdvanced Science, EarlyView.
Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...

Uniaxial Strain‐Driven Ferroelastic Domain Tuning in LaAlO3${\rm LaAlO}_3$

open access: yesAdvanced Science, EarlyView.
The present work demonstrates based on AFM, μ$\umu$‐Raman spectroscopy, XRD, and first‐principles, that uniaxial strain provides a handle for tuning the ferroelastic domain populations in lanthanum aluminate, driving a continuous and controlled phase transition from a four‐variant rhombohedral crystal system to a two‐variant orthorhombic crystal system

Suppressing Photothermal Artifacts in Flexible Fluorescent Fiber‐Optic Sensors for Accurate and Precise In Situ Temperature Monitoring

open access: yesAdvanced Science, EarlyView.
A partial‐inner‐cladding optical fiber (PICOF) is developed to suppress photothermal artifacts in fluorescent fiber‐optic thermometry by isolating the sensing layer from regions prone to photothermal effects. This structural design strategy enables high‐fidelity operation at elevated excitation power, achieving high accuracy (maximum absolute error ...

3D Bioprinted Blood–Brain–Tumor Barrier Spheroid‐Based In Situ Evaluation of Anticancer Compounds Against Glioblastoma: ROS‐Producing Ruthenium as a Potential Therapeutic Candidate

open access: yesAdvanced Science, EarlyView.
The blood–brain–tumor barrier (BBTB) penetration by anticancer drugs and their effects on glioblastoma (GBM) is assessed using 3D bioprinted‐spheroids. Anticancer drug‐induced U‐87 MG cell death is quantified through in situ imaging of spheroids using a cancer cell death probe. The Ru compound, a partial P‐gp substrate, induces greater tumor‐cell death
