- Dynamic coacervates offer potential for controlled molecular interactions and phase separation.
Purpose of the Study:
- To engineer a dynamic multiphase coacervate system for selective molecular partitioning.
- To create a pH-responsive platform for separating enzymatic products based on polarity.
- To enhance the colloidal stability of coacervate systems for sustained applications.
Main Methods:
- Fabrication of a dynamic multiphase coacervate system.
- Investigation of pH-responsive behavior for molecular separation.
- Assessment of colloidal stability and product partitioning efficacy.
- Evaluation of catalytic performance within the coacervate system.
Main Results:
