Colloidal polyaniline dispersions: Antibacterial activity, cytotoxicity and neutrophil oxidative burst

- The biological activity of colloidal polyaniline was determined for the first time.
- The cytotoxicity threshold of the colloid was of 150 μg mL−1.
- The human neutrophils were not activated by colloid.
- Colloidal polyaniline has scavenging effect on already formed reactive oxygen species.
- Antibacterial activity of polyaniline colloid was low.
