Monitoring the Transition from Spherical to Polymer‐like Surfactant Micelles Using Small‐Angle X‐Ray Scattering

Abstract: Despite over a century of modern surfactant science, the kinetic pathways of morphological transitions in micellar systems are still not well understood. This is mainly as a result of the lack of sufficiently fast methods that can capture the structural changes of such transitions. Herein, a simple surfactant system consisting of sodium dodecyl sulfate (SDS) in aqueous NaCl solutions is investigated. Combining synchrotron radiation small-angle X-ray scattering (SAXS) with fast stopped-flow mixing schemes allow… Show more

“…Particle stability was confirmed when no changes in the correlation data were observed during incubation under physiological conditions. Indeed, sodium dodecyl sulfate (SDS) micelles only undergo spontaneous morphological transitions when [NaCl] reached 1 m , which is well above physiological conditions . The critical aggregation concentration (CAC) was determined using a 1‐anilino‐8‐naphthalenesulfonate (ANS) assay.…”

“…Indeed, sodium dodecyl sulfate (SDS) micelles only undergo spontaneous morphological transitions when [NaCl] reached 1m, which is well above physiological conditions. [25] The critical aggregation concentration (CAC) was determined using a 1-anilino-8-naphthalenesulfonate (ANS) assay. CAC values of SMs were measured at ≈0.030 mg mL −1 (2.7 × 10 −6 m), with NWs displaying a slightly lower CAC at ≈0.022 mg mL −1 (2.0 × 10 −6 m) ( Figure S33, Supporting Information).…”
