An Inflammation‐Targeting Engineered Probiotic Escherichia coli Nissle 1917 with High Anti‐TNF‐α Nanobody Secretion Efficacy Alleviates Ulcerative Colitis

Advanced Science, EarlyView.
Ulcerative colitis therapy requires precise drug targeting. This study engineers a probiotic E. coli Nissle 1917 to surface‐display ANXA5, enabling specific binding to phosphatidylserine (PS) exposed on inflamed colonic epithelium for enhanced targeting and colonization.

Near‐Infrared Switch‐Driven Macrophage Dynamically Reprogramming for Anti‐Infection and Tissue Healing on Polyetheretherketone Implants

Advanced Science, EarlyView.
This study develops a Mg‐H‐SPEEK implant with NIR‐switchable immunomodulatory properties. Under NIR, it promotes M1 macrophages for antibacterial action; without NIR, it induces M2 reprogramming to enhance tissue healing. This dual‐function material offers a smart strategy for reducing infection and improving integration in percutaneous implants ...

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

Advanced 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.

Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

Advanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Chromatic‐Zone Mapping for Rapid Discovery of Antibacterial Alloys with Nanostructured Surfaces

Advanced Science, EarlyView.
A high‐throughput parallel chromatic‐zone screening strategy that enables the simultaneous screening of alloy composition and surface structure. Ultimately linking surface color, composition, and morphology with antimicrobial performance enables the screening and prediction of color zones, thereby reducing characterization requirements by 90% and ...

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

Advanced 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.

Phenylboronic Acid‐Modified Copper Nanozymes as Nanoscavengers of Bacterial Polysaccharides Causing Acute Lung Injury

Advanced Science, EarlyView.
A novel copper nanocluster coated with 4‐mercaptobenzeneboronic acid (CuMPBA) is developed to target bacterial polysaccharides for addressing complicated acute lung injury (ALI) caused by severe burns and early pulmonary infections. CuMPBA exhibits dual anti‐inflammatory and antibacterial mechanisms by: (a) binding and degrading toxic bacterial ...
