Multiscale Cross-Linking via Polysaccharide-Assisted Robust Zwitterionic Hydrogel Interface Enabling Electrochemical Sensing in Complex Serum.

The serious fouling layer from the nonspecific adsorption in complex media would greatly impair the analytical performance and even lead to the complete failure of the electrochemical sensor. Zwitterionic hydrogel has been demonstrated to possess exc…
