Panels correspond to the conditions shown in <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1014588#ppat.1014588.g006" target="_blank">Fig 6</a>: (A) Dr⁺ bacteria attached to untreated polystyrene and (B) Dr⁻ bacteria attached to untreated polystyrene. Labels indicate air (a), meniscus (m), and bacteria (b). Recordings were acquired for 80 sec at 5 frames per second. Both bacterial variants were detached from untreated polystyrene by capillary forces generated by the receding meniscus. In the Dr⁺ sample, detached cells were immediately transported within the meniscus and accumulated at the wetting arm contacting the upper glass coverslip, where they adhered efficiently, resulting in visible bacterial accumulation behind the receding meniscus.</p> <p>(MP4)</p> 2026-09-16T17:55:57Z Dataset Media 10.1371/journal.ppat.1014588.s024 https://figshare.com/articles/media/_p_Detachment_of_Dr_sup_sup_and_Dr_sup_sup_bacteria_from_untreated_polystyrene_by_a_receding_meniscus_p_/33867587 CC BY 4.0
