Trimetallic Nanozyme‐Embedded Smart Hydrogel Enables NIR‐Controlled Bacterial Killing and Oxidative Stress Alleviation

open access: yesAdvanced Science, EarlyView.
A microenvironment‐responsive hydrogel is developed incorporating polymyxin B‐modified AuMnCu nanozymes and dual drugs (tannic acid and tobramycin). At infection sites, it generates ROS, releases drugs responsively, and enhances mild photothermal action to disrupt bacterial redox balance.

An Interpretable SERS–AI Platform for Rapid and Quantitative Diagnosis of Polymicrobial UTIs: Powered by Positively Charged Plasmonic Nanoparticles and Attention‐Based Deep Learning

open access: yesAdvanced Science, EarlyView.
This work introduces a label‐free SERS‐AI platform for rapid and interpretable diagnosis of polymicrobial urinary tract infections. By integrating Au@Ag@bPEI substrates with a CNN‐CBAM model, the system enables accurate bacterial identification and proportion prediction, while highlighting biologically relevant Raman features.

Nanoscopic Mapping of the Extracellular Space in Amyloid Plaque‐rich Cortex

open access: yesAdvanced Science, EarlyView.
The extracellular space and diffusion around amyloid plaques are examined using shadow imaging and single‐particle tracking. Increased diffusivity is found near plaques, extracellular matrix alterations, and plaque core penetrability that varies with amyloid phenotype.

Reinstating Niche Failure in Diabetic Cranial Defects via Chronotaxic Signal‐Amplifying Fluidic Biomimetic Hydrogel

open access: yesAdvanced Science, EarlyView.
An in situ moldable GelSSO/PDA@SDF hydrogel functions as a chronotaxic signal‐amplifying biomimetic niche to restore regenerative failure in diabetic cranial defects. By sequentially releasing SDF‐1α‐loaded PDA nanoparticles and osteoinductive oligodeoxynucleotides, it orchestrates immunomodulation, progenitor recruitment, angiogenesis, and ...
