Complex coacervate microdroplets can be stabilized by comb polyelectrolytes and used as encapsulants for biological molecules such as proteins. In this thesis, we aim to create complex coacervate microdroplet dispersions with narrow size dispersity distributions by optimizing the concentrations and the molecular weights of homopolyelectrolytes and comb polyelectrolytes. The particle size distribution of suspended droplets is analyzed using static light scattering and microscopy. Further, we study the effect of mechanical processing (centrifugation and continuous stirring) on the particle size distribution of the complex coacervate microdroplets. Additionally, we investigate the reusability and recyclability of the complex coacervate microdroplet dispersions. Our process can potentially advance the use of complex coacervate microdroplets as synthetic reactor media for continuous stirred-type bioreactors.
