Abstract

This paper highlights the potential benefits of using self-assembled polymeric nanoparticles of various shapes to enhance drug uptake. First, we highlight the growth and development of the polymersome, using a liposome as a blueprint for amphiphilic codelivery. Then, we focus on the advantages of nanoparticle elongation, drawing from the field of solid nanoparticles, as opposed to self-assembled vesicles which have not yet been extensively explored in shape-modulated drug delivery applications. Notably, regardless of the material used in the solid nanoparticle systems, more elongated shapes lead to greater cellular uptake, decreased interaction with the reticuloendothelial system macrophages, and increased circulation times. Finally, we highlight the methods currently being developed to modulate polymersome shape, thus providing a drug delivery system with the benefits derived from amphiphilicity and elongated structures. Current methods employed to modulate polymersome shape involve osmotic pressure gradients, solvent switching, and the use of cross-linking agents. Although these methods are successful in modulating polymersome shapes and the benefits of elongated nanoparticles in therapeutic targeting are clear, these methods have not yet been explored for applications in drug delivery.
