Catalysis of the electrochemical reduction of oxygen by bacteria isolated from electro-active biofilms formed in seawater [PDF]

, 2011
Biofilmsformed in aerobic seawater on stainless steel are known to be efficient catalysts of the electrochemicalreduction of oxygen. Based on their genomic analysis, seven bacterial isolates were selected and a cyclic voltammetry (CV) procedure was ...

Engineering a Virus‐Derived X Family DNA Polymerase FvPolX for de novo DNA Synthesis

Advanced Science, EarlyView.
In this study, a Faustovirus‐derived polymerase (FvPolX) is engineered based on structural and sequence analysis of PolX enzymes. The optimal mutants demonstrate substantially enhanced catalytic activity toward dNTPs and 3′‐ONH2‐dNTPs compared to the wild‐type enzyme.

Mechanistic Design of Graphdiyne‐Based Multimodal Sensing Integrating Machine Learning and Photothermal Dynamics for Precision Recognition and On‐Demand Inactivation

Advanced Science, EarlyView.
A triple‐mode theranostic platform enables integrated electrochemical, colorimetric, and photothermal detection of bacterial infection. Glucose oxidation triggers H2O2 generation and TMB oxidation to oxTMB, producing color and thermal signals under 808 nm NIR irradiation.

Microplastics in marine pollution: Oceanic hitchhikers for the global dissemination of antimicrobial-resistant bacteria

One Health
Microplastics (MPs) are globally anthropogenic contaminants of marine environments. Bacteria can colonize MPs forming biofilms that constitute the plastisphere. Carbapenem-resistant bacteria in plastisphere could be a hidden threat for marine life.
