We report a unique bio-nanomechanical behavior at the septum (Z-ring) of Streptococcus
mutans-containing biofilm through in situ measurements obtained by atomic force …

Atomic force microscopy (AFM) has garnered much interest in recent years for its ability to
probe the structure, function and cellular nanomechanics inherent to specific biological cells …

Knowledge of mechanical properties and failure mechanisms of biofilms is needed to
determine how biofilms react on mechanical stress. Methods currently available cannot be …

Insight into live microbial biofilm microstructure and mechanical properties and their
interactions with the underlying substrate can lead to the development of new remedial …

Streptococcus mutans is one of the main pathogens that cause tooth decay. By metabolizing
carbohydrates, S. mutans emits extracellular polymeric substance (EPS) that adheres to the …

Streptococcus mutans (S. mutans) is a group of cocci bacteria that highly contributes to oral
decay. In cases of high potency, it can cause plaque build-up, impaired speech, difficulty …

We took benefit from Atomic Force Microscopy (AFM) in the force spectroscopy mode to
describe the time evolution–over 24 h–of the surface nanotopography and mechanical …

Bacterial biofilms were imaged by atomic force microscopy (AFM), and their elasticity and
adhesion to the AFM tip were determined from a series of tip extension and retraction cycles …

Scanning probe microscopy techniques are powerful tools for studying the nanoscale
surface properties of biofilms, such as their morphology and mechanical behavior. Typically …

Bacterial adhesion to a surface is the first step in biofilm formation, and adhesive forces
between the surface and a bacterium are believed to give rise to planktonic-to-biofilm …
