Diffusion of Nanoparticles in a Biofilm
Abstract
In order to evaluate the risk of engineered nanomaterials in the natural environment, one must determine their mobility, among other factors. Such determinations are difficult given that natural systems are heterogeneous and biofilms are ubiquitous in soils and waters. The interaction and diffusion of several model nanoparticles (dextrans, fluorescent microspheres, Ag nanoparticles) were studied in situ using confocal microscopy and fluorescence correlation spectroscopy in a biofilm composed of Pseudomonas fluorescens. For the most part, relative self-diffusion coefficients decreased exponentially with the square of the radius of the nanoparticle. The precise growth conditions of the biofilm resulted in a variable density of both exopolymers and microbes, which was also shown to be an important parameter controlling the diffusion of the nanoparticles. Finally, the charge of the nanoparticles appeared to be important; for a dense bacterial biofilm, a greater than predicted decrease in the self-diffusion coefficient was observed for the negatively charged nano Ag.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
