Incorporation of proteins into complex coacervates

Area of Science:

• Materials Science
• Biochemistry
• Physical Chemistry

Background:

• Complex coacervates are liquid-phase separated materials formed by oppositely charged polymers.
• They have diverse applications, including drug delivery, food science, and biomimetic compartments.
• Understanding their behavior is crucial for optimizing their use.

Purpose of the Study:
