Conventional methods fail to analyze active surfactants. This review introduces a new framework linking surfactant structure and interfacial behavior for better biointerface analysis.
Area of Science:
- Surface Chemistry
- Analytical Chemistry
- Biophysical Chemistry
Background:
- Surfactant function in biointerfaces depends on complex factors beyond bulk concentration.
- Traditional analytical methods often miss chemically intact, active surfactant fractions.
Purpose of the Study:
- To present an integrated, biointerface-centered analytical framework for surfactants.
- To link surfactant molecular architecture and interfacial phenomena to analytical strategies.
- To improve characterization of surfactants in complex biological systems.
Main Methods:
- Integrating distribution-resolved compositional analysis with interface-responsive techniques.
- Probing adsorption dynamics, interfacial rheology, and membrane perturbation.
- Utilizing multidimensional and AI data-integrated workflows for analysis.
Main Results:
- The framework resolves compositional heterogeneity and detects transformation products.
- It distinguishes active from inactive surfactant populations under non-equilibrium conditions.
- New approaches extend analysis beyond conventional calibration-based methods.
Conclusions:
- Redefining surfactant characterization as a compositional-functional problem is key.
- This approach enables mechanistic and translationally relevant understanding of surfactants.
- The framework aligns analytical resolution with interfacial complexity and system behavior.
