Elements of Surface Activity

Key Aspect of Surface Activity Technique Ideal Features of Mimic
Monolayer-phase behavior and lipid respreading LWSB (i) Early lift-off (> 100 Å2/molecule)
(ii) Biomimetic plateau region between 40–55 mN/m
(iii) High maximum surface pressure near 72 mN/m
(iv) No significant hysteresis between successive surface area compressions
Surface film morphology as a function of surface pressure FM (i) LC domain size ~ 25 μm2
(ii) Bright film domains appear upon film compression
Rapid adsorption to air-water interface Static PBS Reach surface tension <25 mN/m in <1 min
Reduce and control surface tension as a function of surface area Dynamic PBS (i) Low (near zero) minimum surface tension with minimal compression (low compressibility)
(ii) Low maximum surface tension
(iii) No significant hysteresis between successive compression-expansion loops
