    Bacterial motility can be quantified using a diffusivity parameter. A new capillary assay offers a fast, simple, and accurate method for assessing bacterial movement and population motility.

    Area of Science:

    • Microbiology
    • Biophysics

    Background:

    • Bacterial motility is crucial for various biological processes.
    • Quantifying bacterial movement is essential for understanding population dynamics.

    Purpose of the Study:

    • To propose bacterial motility be represented by a diffusivity parameter.
    • To introduce a novel capillary assay for measuring this parameter.

    Main Methods:

    • Development of a simple capillary assay.
    • Quantification of bacterial motility using the assay.

    Main Results:

    • The assay successfully quantifies the diffusivity parameter of bacterial populations.
    • Initial results demonstrate the assay's effectiveness.
