Visualising diverse extracellular nucleic acids in biofilms with DNA-binding dyes

This paper evaluates DNA-binding dyes for visualizing non-canonical extracellular nucleic acids in biofilms and identifies dyes with specific binding preferences.

Spatial organization of self-assembled G-quadruplex nucleic acids tunes extracellular electron transfer in pathogenic biofilms

This study shows that Staphylococcus aureus biofilms naturally assemble G4-rich extracellular nucleic acids that facilitate electron transfer, with spatial organization influencing electroactivity.

Secret life of prophages: template-directed synthesis of DNA superstructures via prophage activation and rolling circle replication in bacterial biofilms

This paper demonstrates that prophages can be used to synthesize functional extracellular DNA superstructures via rolling circle replication in bacterial biofilms.

The host environment rather than biofilm growth activates stress responses and conveys ciprofloxacin tolerance in Staphylococcus aureus

This study shows that the host environment, not biofilm growth, activates stress responses in Staphylococcus aureus and leads to ciprofloxacin tolerance at the single-cell level.

Hemin-binding DNA structures on the surface of bacteria promote extracellular electron transfer

This study shows that hemin-binding G-quadruplex DNA structures in bacterial biofilms facilitate extracellular electron transfer and peroxidase-like activity.

Extracellular RNA drives Electromethanogenesis in a Methanogenic Archaeon

The paper shows extracellular RNA facilitates electron transfer in Methanosarcina barkeri, enabling electromethanogenesis, and suggests RNA-based electron transfer may be ancestral.

Dental biofilms contain DNase I-resistant Z-DNA and G-quadruplexes

This study identifies DNase I-resistant Z-DNA and G-quadruplexes in dental biofilms, suggesting new targets for biofilm control.

Mitomycin C Retains Efficacy after Adaptive Laboratory Evolution of Staphylococcus aureus

This study shows mitomycin C retains efficacy against Staphylococcus aureus resistance even after adaptive evolution, especially when combined with rifampicin.
