Abstract
This dataset supports the manuscript “Biofilm Formation Promotes Microplastic Mobility via Hydrodynamic Forces.” It includes measurements of biofilm area and the percentage of transported beads under five different flow rates, as well as an example set of microscopy images and a MATLAB dataset used for image processing. In the manuscript, we demonstrate that the presence of biofilms alters the hydrodynamic forces acting on microplastic particles. Specifically, biofilms modify the local pressure field and generate lift forces strong enough to mobilize particles even under weak shear conditions.
Description
The microscopy images were captured using a confocal microscope. The MATLAB code was used to process these images to quantify the biofilm area and identify transported beads. All resulting measurements are compiled and summarized in the spreadsheet.
