WebMay 23, 2024 · The spatiotemporally ordered release manner and pharmacokinetic complementarity of ROS and NO improve the anti-biofilm outcome synergistically. Abstract The heterogeneity in biofilms is a major challenge in biofilm therapies due to different susceptibility of bacteria and extracellular polymeric substances (EPS) to antibacterial … WebBiofilm eradication by ROS-forming procedures. Biofilms are dense layers of microbial communities attached to different surfaces. 97 Bacteria in biofilm environments express character differently than planktonic forms, for example, decreased susceptibility to antimicrobial agents. Therefore, biofilms may act as a niche for the recurrence of ...
