Forces between oil drops in polymer-surfactant systems: Linking direct force measurements to microfluidic observations

The interaction behaviour between the force measurements and the microfluidic observations showed a strong correlation, where the observed adhesion between drops in the microfluidics is sensitive to the drop deformation and Laplace pressure. Correlation between the two techniques provides insight into the surface forces between drops in flowing systems and has potential utility in the formulation of emulsions.
