Amine-functionalized polyurethane foams via phase inversion for colorimetric detection of Escherichia coli in liquids

Key Points

• The aim is to develop amine-functionalized polyurethane foams for colorimetric detection of Escherichia coli in liquids.
• Utilized phase inversion to create amine-functionalized polyurethane foams.
• Immobilized X-Gluc to achieve a specific chromogenic response to E. coli.
• Evaluated water absorption, capillarity, and stability for potential monitoring applications.
• Achieved specific colorimetric response to E. coli upon X-Gluc immobilization.
• Functionalization led to improved water absorption and stability of the foams.
• Demonstrated potential use for point-of-care diagnostics in liquid monitoring.
