Edible and Recyclable Gelatin‐Based Electronics for High‐Precision Health and Environmental Monitoring

Advanced Science, EarlyView.
An edible and recyclable composite film composed of gelatin and activated charcoal is presented for multifunctional health and environmental monitoring. The edible films exhibit tuneable mechanical and electrical properties, along with multimodal sensing capabilities for strain, humidity, and temperature. The composite film is degradable and recyclable,

Loss of SeqA confers low-level fluoroquinolone resistance through transcriptional reprogramming and RpoS dependence in E. coli

AIMS Microbiology
SeqA is a key regulator of DNA replication initiation and chromosome cohesion in Escherichia coli. Loss of SeqA causes replication asynchrony, segregation defects, and growth delay, but its role in antibiotic susceptibility has remained unclear ...

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

Advanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

Bacteria under SOS evolve anticancer phenotypes

Infectious Agents and Cancer, 2010
Background The anticancer drugs, such as DNA replication inhibitors, stimulate bacterial adhesion and induce the bacterial SOS response. As a variety of bacterial mutants can be generated during SOS, novel phenotypes are likely to be selected under the ...

Molecular Cages as Probes in Indicator Displacement Assays: The Case of Scopolamine Detection

Angewandte Chemie, EarlyView.
In this research, we show the concept of molecular cages as probes in indicator displacement assays, focusing on scopolamine detection, a drug often used in drug‐facilitated sexual assaults. Drug sensing occurs via the drug‐induced transformation of non‐emissive [Fluorescein2⊂Cage] complex into [Scopolamine⊂Catenane] and highly emissive free ...
