Figure 1. A Polymersome Protocell.
Polymersomes can be used as a template to create cell-like structures. Creating an autonomous particle that mimics the diverse behaviors of a cell will require incorporation of biological functionality in the membrane, the ability to trigger responses, autonomous movement, and morphological changes. Many of these functions will require organized metabolic reactions and gene expression to be housed within distinct spatial environments in the polymersome.
