Antifouling binary liquid-infused membranes for biological sample pretreatment.

Hydrophobic membranes infused with mixed solvents including a low polar solvent and a specific solvent can efficiently separate analytes from blood upon applying a voltage. In contrast, membranes infused with a specific solvent alone show significantly reduced separation efficiencies for blood samples. Infusion of a low polar solvent is of importance for achieving antifouling ability of membranes for biological sample pretreatment. [ABSTRACT FROM AUTHOR]
