To validate the QPI method's accuracy against theoretical models.

Main Methods:

Utilized quantitative phase imaging (QPI) to visualize microfluidic mixing.
Employed various polydimethylsiloxane (PDMS) microfluidic channels with different geometries.
Validated results by comparing QPI concentration maps with theoretical calculations based on Fick's law.

Main Results:

Successfully achieved label-free, quantitative imaging of microfluidic mixing.
Generated accurate concentration maps within microfluidic channels of varying designs.
Demonstrated strong agreement between experimental QPI data and Fick's law predictions.

Conclusions:

Quantitative phase imaging is a powerful tool for label-free analysis of microfluidic mixing.
The presented QPI method provides accurate, quantitative concentration data.
This technique offers a viable alternative to traditional imaging methods in microfluidics research.
