Zwitterionic membranes

Zwitterionic membranes are specialized biological or synthetic structures made up of molecules that have both positive and negative charges but are overall electrically neutral. These membranes mimic the properties of natural cell membranes, providing excellent resistance to contamination, fouling, and unwanted interactions with other substances. Their unique charge balance allows them to repel bacteria, proteins, and other pollutants while allowing desirable molecules, such as water or specific ions, to pass through. This makes zwitterionic membranes highly effective in filtration, sensors, and biomedical applications, offering durability and selectivity by leveraging their balanced charge properties.
