Efficient Protein Encapsulation within Thermoresponsive Coacervate-Forming Biodegradable Polyesters.

Presented here is a novel method for encapsulating proteins into biodegradable, thermoresponsive coacervate-type polyesters. Bovine serum albumin (BSA) was efficiently incorporated into coacervate droplets via a simple thermoresponsive encapsulation mechanism. Tunable modular systems for encapsulation such as the one presented here may be useful in a range of protein delivery applications.
