Research data to "Monitoring of osmotic swelling induced filling degree changes in WOW double emulsions using Raman technologies"

However, the complex, nested structure negatively affects the stability of double emulsions. Still there is a lack of suitable measurement technology to fundamentally understand the cause of the instability mechanisms taking place.

This study presents a novel measurement method to continuously track filling degree changes due to water diffusion in a water-in-oil-in-water (W1/O/W2) double emulsion droplet. The measurement method is based on the Raman effect and provides both photometric and spectrometric data. No sample preparation is required, and the measurement does not affect the double emulsion droplet.
