Antimicrobial zwitterionic hydrogel coatings for kidney disease-associated catheters: current challenges and advances.
Zwitterionic hydrogel coatings comprise three-dimensional networks of zwitterionic polymers that bear balanced anionic and cationic groups. These coatings exhibit superior hydration capacity, high drug-loading efficiency, excellent biocompatibility, and remarkable salt resistance. As a result, they have demonstrated si...
