Single-cell approach dissecting agr quorum sensing dynamics in Staphylococcus aureus

The paper uses single-cell techniques to study agr quorum sensing dynamics in Staphylococcus aureus, revealing differences in AIP sensitivity and community interaction patterns across agr-types.

The role of cellular filamentation in bacterialaggregation and cluster-cluster assembly

This study investigates how bacterial filamentation affects aggregate formation, network connectivity, and mechanical properties through experimental and computational analysis.

A microfluidic platform for characterizing the structure and rheology of biofilm streamers

This paper introduces a microfluidic platform to study biofilm streamer structure, morphology, and rheology under controlled conditions.

The role of surface adhesion on the macroscopic wrinkling of biofilms

This study investigates how surface adhesion affects biofilm wrinkling in Pseudomonas aeruginosa under flow, showing mechanical buckling leads to channel formation that enhances biofilm volume and bacterial movement.

The structural role of bacterial eDNA in the formation of biofilm streamers

This study shows that extracellular DNA (eDNA) forms the backbone of Pseudomonas aeruginosa biofilm streamers and is essential for their mechanical stability, with exopolysaccharide Pel playing an indirect role.

Dynamic arrest and aging of biomolecular condensates are regulated by low-complexity domains, RNA and biochemical activity

This study uses DDM to analyze how material properties of P-body condensates are regulated by RNA structure, enzymatic activity, and other factors.

The effect of flow on swimming bacteria controls the initial colonization of curved surfaces

This study shows that flow conditions control where motile bacteria attach to curved surfaces, with attachment preferentially occurring on leeward sides and downstream of apexes, and increases attachment rates by up to two orders of magnitude compared to non-motile cells.
