Poly(sulfobetaine methacrylate) (PSBMA) is a well-known zwitterionic polymer, it is non-toxic and biocompatible. On each of its repeating unit, it carries both a positive charge and a negative charge, leading to its strong hydration capacity. Surfaces coated with PSBMA showed superhydrophilic property and strong resistance to protein adsorption/bacterial adhesion, making this polymer a promising material in anti-fouling applications.

Zwitterionic poly(sulfobetaine methacrylate) (PSBMA) has been well studied for its superhydrophilic and ultralow biofouling properties, making it a promising material for superabsorbent and nonadherent wound dressings. Electrospinning provides multiple desirable features for wound dressings, including high absorptivity due to high

Zwitterionic molecules have been widely studied as coating materials for preparing anti-fouling surfaces because they possess strong hydration properties that can resist non-specific protein adsorption. Numerous studies on surface modification using zwitterionic molecules have been investigated, such as electrochemically mediated
