Fundamentals and applications of zwitterionic antifouling polymers (2019, background): “Study of the ultra-low-fouling zwitterionic hydrogels (polyCBMA) had demonstrated that the gel could resist capsule formation for 3 months in mice, as compared to the commonly used polyHEMA hydrogels that was fully encapsulated by collagens after 4 weeks (figure 10(b)) [45].”
