Hemocompatibility and anti-biofouling property improvement of poly(ethylene terephthalate) via self-polymerization of dopamine and covalent graft of zwitterionic cysteine

- Cysteine immobilized PET endowed with improved resistance to nonspecific protein adsorption and platelet adhesion.
- Cysteine immobilized PET had low hemolytic ability.
- Cysteine immobilized PET could greatly inhibit HeLa cell adhesion.
