Figure Lengend Snippet: (A) A micrograph of red fluorescent 1 μm PS microplastics adsorbed on a free-standing lipid bilayer (bar is 100 μm). (B) The adsorption isotherm of 1 μ m PS (yellow circles) microplastics, incubated in seawater with 0.014% volume of hexane, adsorbed on a free-standing lipid bilayer. Blue circles are plots for 1 μm PS microplastics incubated in seawater plus hexane, which are adsorbed on a free-standing lipid bilayer. (C) The extracted MSD as a function of time on a log–log scale, for a 1 μm PS incubated in hexane. The measured average microplastic diffusion coefficient D ≈ 0.6 μm ·s –1 . (D) Bilayer tensions measured similar to Figure C, except that PS microplastics were incubated in seawater in the presence of hexane. The experimental data are represented as bar plot, while the continuous line represents the theoretical plot. It was obtained using the surface coverage data plotted in (B).
Article Snippet: Red fluorescent polystyrene microplastic beads (PS) were purchased from Thermo Fisher (R0100), with a diameter 1 μm.
Techniques: Adsorption, Incubation, Diffusion-based Assay
