Quantification of Antibiotic Diffusion in Biofilms Using Gold Nanostar Surface‐enhanced Raman Spectroscopy

Advanced Science, EarlyView.
Gold nanostar‐enhanced Raman spectroscopy (SERS) enables real‐time, label‐free tracking of levofloxacin diffusion in intact biofilms. Nanostars embedded 16 µm below the surface detect drug arrival over time, revealing the impact of the biofilm matrix on antibiotic transport. Abstract The increased resistance to antibiotics shown by bacteria in biofilms

Novel Role of Gut‐Derived Roseburia Intestinalis in Safeguarding Intestinal Barrier Integrity and Microenvironment Homeostasis During Arsenic Exposure

Advanced Science, EarlyView.
Arsenic exposure disrupts intestinal barriers and gut microenvironment. Fecal microbiota transplantation (FMT) alleviates arsenic‐induced damage, with gut‐derived Roseburia intestinalis (R.i) identified as a key protective strain. R.i administration counters arsenic toxicity through immunomodulatory pathways and metabolites.

Nanoparticle‐Functionalized Cellulose Through Biosynthesis‐Only Approach

Advanced Science, EarlyView.
This study reports the first covalent incorporation of glucose‐modified carbon dots (Glu‐CDs) into bacterial cellulose (BC) via microbial fermentation, resulting in BC nanofibers that exhibit uniform cyan fluorescence. A 3D‐printable hydrogel (Glu‐CDs‐BC‐SA) is developed, facilitating the fabrication of fluorescent structures. This work demonstrates an

Chronic PET‐Microplastic Exposure: Disruption of Gut–Liver Homeostasis and Risk of Hepatic Steatosis

Advanced Science, EarlyView.
Chronic exposure to environmentally relevant PET microplastics disrupts gut–liver homeostasis, leading to hepatic steatosis, early fibrosis, and altered gut microbiota. These effects signal metabolic imbalance and gut–liver axis impairment, emphasizing chronic microplastic ingestion as an emerging environmental health risk linked to non‐communicable ...

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.
