Embedding fluorescent beads within biofilm

WebJan 13, 2024 · Within a biofilm, a sticky glue-like substance called the matrix binds the cells to each other and to the surface. Cells that make the matrix typically have an advantage over those that do not because they can better resist the shearing forces experienced when liquid flows over the surface. WebMar 23, 2024 · The process of paraffin-embedding and thin-sectioning biofilms follows a simple logic. First, the biofilms are encased in a layer of agar to preserve morphology during processing. Second, the encased-biofilms are submerged in a fixative to crosslink macromolecules and preserve micromorphology.
