ResumoAbstract Polymersomes are self‐assembled polymer shells composed of block copolymer amphiphiles. These synthetic amphiphiles have a similar amphiphilicity to lipids, but they have much larger molecular weights and so for this reason, plus many others reviewed here, comparisons of polymersomes to viral capsids composed of large polypeptide chains seem increasingly more appropriate. The wide range of polymers being used to make polymersomes is summarized together with descriptions of physical properties such as stability and permeability. Emerging studies of in vivo stealthiness and programmed disassembly for controlled release are also elaborated here together with a summary of targeting in vitro. Comparisons of polymersomes to viral capsids are shown to encompass many aspects of current designs. Drug Dev. Res. 67:4–14, 2006. © 2006 Wiley‐Liss, Inc.
