The benefit of these coatings is that they are primarily non-leaching coatings and therefore demonstrate long-term intrinsic antibacterial activity, are biocompatible, and do not cause any significant cytotoxicity.…”

“…Beyond QASs, different cationic polymer brushes such as polyethyleneimine (PEI) have been grafted onto polyurethane catheters to prevent bacterial adhesion and biofilm formation. 45 The rationale behind using cationic polymers is that they are capable of penetrating the negatively charged membranes of bacterial cells ultimately causing necrosis. 76 Specifically, Gultekinoglu et al 45 modified the PEI brushes with bromohexane to improve their ability to disrupt bacterial membranes.…”
