Coacervates can be used for various applications, from catalysis to 3D bioprinting, biosensing applications, deposition of pesticides, and formation of underwater adhesives. They can also be used for different biomedical applications such as drug delivery, protein delivery, and drug protection. In delivery applications, coacervates can be advantageous because of their encapsulation ability. Additionally, they can be especially useful if they can protect the encapsulated material from degradation due to oxidation or exposure to UV light.
