Liposomes and polymersomes: a comparative review towards cell mimicking

Area of Science:

• Synthetic biology
• Biomimetic systems
• Protocell research

Background:

• Cells compartmentalize life via plasma membranes, but complex organisms necessitate simplified models.
• The bottom-up approach in synthetic biology aims to build artificial cells (protocells) from basic components.
• Model membranes, including liposomes and polymersomes, are crucial for constructing these protocells.

Purpose of the Study:

• To compare and contrast liposomes and polymersomes for designing artificial cell models.
• To understand the advantages and disadvantages of each vesicle type.
• To review current developments in liposome and polymersome research for synthetic biology.

Main Methods:

• Comparative analysis of liposome and polymersome properties.
• Review of synthesis and self-assembly techniques for both vesicle types.
• Examination of diverse applications in synthetic biology and beyond.

Main Results:

• Liposomes offer biocompatibility but limited stability; polymersomes provide enhanced stability and tunable properties.
• Synthesis and self-assembly methods vary, impacting vesicle characteristics and scalability.
• Both vesicle types have distinct advantages for specific applications in artificial cell research.

Conclusions:

• Choosing between liposomes and polymersomes depends on the specific requirements of the protocell model.
• Further research can optimize vesicle design for advanced biomimetic functionalities.
• This comparison aids in the rational design of protocells for fundamental biological studies and applications.
