| Research Abstract |
To remove endotoxin from water, we plan to develop polymer hydrogels that selectively adsorb endotoxin. We successfully prepared polymer hydrogels with endotoxin-binding sites by applying a molecular imprinting technique and using amino acid derivatives or tripeptide derivatives as functional monomers. The hydrogels obtained selectively adsorbed endotoxin even in a coexistence of the other substances, and after adsorption of endotoxin to the hydrogels was completed the hydrogels could be regenerated by washing with acidic and basic solutions.
