Microbiology is the science of microbes, particularly bacteria. Many bacteria are motile: they
are capable of self-propulsion. Among these, a significant class execute so-called run-and …

Solutions of different polymers in the same solvent are incompatible as a rule and show
phase separation when they are mixed. H incompatibility is also to be observed in systems …

In cystic fibrosis (CF) airways, Pseudomonas aeruginosa forms cellular aggregates called
biofilms that are thought to contribute to chronic infection. To form aggregates, P. aeruginosa …

We review physically-motivated studies of bacterial near-surface motility driven by flagella
and type IV pili (TfP) in the context of biofilm formation. We describe the motility mechanisms …

Adding a nonadsorbing polymer to passive colloids induces an attraction between the
particles via the “depletion” mechanism. High enough polymer concentrations lead to phase …

Bacteria causing chronic infections are generally observed living in cell aggregates
suspended in polymer-rich host secretions, and bacterial phenotypes induced by …

The attachment of bacteria to surfaces provides advantages such as increasing nutrient
access and resistance to environmental stress. Attachment begins with a reversible phase …

In 1954, Asakura and Oosawa 1 explained that nonadsorbing macromolecules can induce
attractive forces between colloidal particles in a single page paper in this journal. The …

The exopolysaccharide Psl contributes to biofilm structure and antibiotic tolerance and may
play a role in the failure to eradicate Pseudomonas aeruginosa from cystic fibrosis (CF) …

Secretion of extracellular polymeric substances (EPSs) by growing bacteria is an integral
part of forming biofilm-like structures. In such dense systems, mechanical interactions …
