Reliable Kinetics for Drug Delivery with a Microfluidic Device Integrated with the Dialysis Bag

Area of Science:

• Biomaterials Science
• Drug Delivery Systems
• Microfluidics

Background:

• Dialysis bags are common for monitoring drug release but suffer from accuracy issues.
• Reliable drug release data is crucial for the clinical success of drug delivery systems.
• Existing methods for evaluating drug release from nanocarriers and films require improvement.

Purpose of the Study:

• To develop and evaluate a new MF-dialysis system for accurate drug release studies.
• To compare the performance of the MF-dialysis system against traditional dialysis bags.
• To assess drug release from soy protein isolate nanoparticles and sodium alginate films.

Main Methods:

• Integration of a microfluidic device with a dialysis bag to create the MF-dialysis system.
• Characterization of Artemisia Absinthium extract-loaded nanoparticles using SEM, DLS, and zeta potential.
• Drug release studies conducted on nanoparticles and alginate films using both MF-dialysis and traditional dialysis.
• Data analysis and modeling using SigmaPlot software.

Main Results:

• The MF-dialysis system provided more accurate drug release data, with an exponential model (R² = 0.95).
• Traditional dialysis yielded a power model (R² = 0.99) but showed less drug release over time.
• The MF-dialysis system demonstrated higher drug release from nanocarriers and films compared to the dialysis bag.
• Nanoparticle characterization confirmed successful loading of Artemisia Absinthium extract.

Conclusions:

• The MF-dialysis system is a promising tool for rapid and reliable evaluation of drug delivery systems.
• This new method enhances the accuracy of drug release monitoring from nanocarriers and films.
• MF-dialysis offers a significant improvement over conventional dialysis techniques for drug release studies.
