SEM analysis. P. aeruginosa PA14 untreated (A,B) and treated (C,D) with SN_TAE2020. SEM (A) 3000×, biofilm appears as a dense and smooth-surfaced mass; (B) 5000×, a bacterial cell is adherent to the matrix surface; (C) 3000×, the treatment affects the biofilm surface, and deep holes are seen partially perforating its surface; (D) 5000×, a globular mass of biofilm with a spongy aspect is shown, where bacterial cells are dispersed on its surface or lay detached and sparsely on the surroundings.
