TWEEN-20® is a non-ionic surfactant with hydrophobic alkyl side chains.


In an aqueous environment the components form micelles above the critical micel concentration (at approximately 0.07% in PBS). This is based on hydrophobic interaction. When other hydrophobic components (proteins, gold conjugates etc.) are present these components are likely to get embedded in micellar structures. This has several effects: hydrophobic (background) interactions arelargely suppressed, the added different molecules are slightly increased in size and previously existing hydrophobic complexes are broken up due to surface forces.
