Ability of sodium dodecyl sulfate to transiently stabilize a phospholipid molecular layer
The interaction between sodium dodecyl sulfate (SDS) and a phospholipid (1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC)) molecular layer was investigated experimentally to understand the mixing effect of SDS on biomembranes. Both the SDS concentration-dependencies of the contact angle between a pai...

| description | The interaction between sodium dodecyl sulfate (SDS) and a phospholipid (1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC)) molecular layer was investigated experimentally to understand the mixing effect of SDS on biomembranes. Both the SDS concentration-dependencies of the contact angle between a pair of water droplets in oil and the surface pressure of a DOPC phospholipid monolayer changed at 1~2mM SDS, which was lower than the critical micelle concentration. Attenuated total reflection Fourier transform infrared spectroscopy was used to evaluate the interaction between DOPC and SDS molecules.
•Water in oil droplets and the surface pressure – area isotherm were examined.•A lipid molecular layer was stabilized with a surfactant at ~2mM.•The concentration range was close to the critical micelle concentration.•The interaction between lipid and surfactant was evaluated spectrophotometrically. |
