The preparation of these systems often involves the use of peptides to impart functional characteristics, such as targeting capabilities or stimuli-responsive degradation.
There are various methodologies for achieving this, ranging from traditional film rehydration to more advanced techniques. Notably, microfluidics is a rapid and continuous polymersome preparation method that allows for highly homogeneous size distribution and high-throughput production, which is essential for consistent experimental outcomes.

Evolving Material Designs
Recent research highlights the versatility of these systems. For instance, PICsome were prepared by mixing cationic and anionic oligopeptides fused with hydrophilic blocks, demonstrating that we do not always need complex synthetic polymers to achieve self-assembly. Furthermore, peptide modified polymers prepared by physical or chemical modifications exhibit enhanced endosomal escape and precise targeting.
