In this research, we designed a controllable coacervate system of four peptide derivatives with a minimal sticker-and-spacer motif. The formed coacervates exhibited efficient encapsulation capabilities with strong antioxidant activity that can protect the encapsulated material. The formation and appearance of the coacervates can be controlled as well as their deposition on surfaces. The coacervates can be adjusted in multiple ways by altering various parameters such as the end groups, coacervation process, solution conditions, deposition process, and encapsulated material. This adjustability greatly enhances the potential of this system to be used for applications. For example, the delivery and release of drugs or dietary supplements can be controlled through the stability of the coacervates. Additionally, controlling the size, shape, and concentration of encapsulated material can expand the design of sensors, improving their efficiency. This work utilizes the dynamic properties of coacervates, such as their ability to condensate and encapsulate additional compounds, with the thermodynamic stability of the resulting dried or aged particles.
