Thermostability of model protocell membranes [PDF]

Proceedings of the National Academy of Sciences, 2008
The earliest cells may have consisted of a self-replicating genetic polymer encapsulated within a self-replicating membrane vesicle. Here, we show that vesicles composed of simple single-chain amphiphiles such as fatty acids, fatty alcohols, and fatty-acid glycerol esters are extremely thermostable and retain internal RNA and DNA oligonucleotides at ...

Metal‐Organic Framework Membranes as Biointerfaces for Compartmentalized Soft‐Matter Protocells

Aggregate, Volume 7, Issue 3, March 2026.
Metal–organic framework nanoparticles self‐assemble at coacervate interfaces to form semipermeable, rigid membranes that stabilize protocells and enable compartmentalized reactivity. By integrating porosity, coordination chemistry, and mechanical robustness, metal–organic framework membranes regulate molecular transport, protein localization, and inter‐

Formation and Stability of Prebiotically Relevant Vesicular Systems in Terrestrial Geothermal Environments

Life, 2017
Terrestrial geothermal fields and oceanic hydrothermal vents are considered as candidate environments for the emergence of life on Earth. Nevertheless, the ionic strength and salinity of oceans present serious limitations for the self-assembly of ...

On the Growth Rate of Non-Enzymatic Molecular Replicators [PDF]

, 2011
It is well known that non-enzymatic template directed molecular replicators X + nO ---> 2X exhibit parabolic growth d[X]/dt = k [X]^{1/2}. Here, we analyze the dependence of the effective replication rate constant k on hybridization energies, temperature,

Role of hydrodynamic flows in chemically driven droplet division

New Journal of Physics, 2018
We study the hydrodynamics and shape changes of chemically active droplets. In non-spherical droplets, surface tension generates hydrodynamic flows that drive liquid droplets into a spherical shape.

Toward homochiral protocells in noncatalytic peptide systems

, 2009
The activation-polymerization-epimerization-depolymerization (APED) model of Plasson et al. has recently been proposed as a mechanism for the evolution of homochirality on prebiotic Earth.

Buoyancy‐Driven Flotation and Magnetotaxis of Vesicle‐Based Prototissue Fibers Induced by Oxygen Bubbles under Enzymatic Reactions

ChemSystemsChem, Volume 8, Issue 2, March 2026.
We demonstrate new strategies to induce motility of vesicle‐based prototissue fibers by generating oxygen bubbles under an enzymatic reaction. The prototissue fibers exhibited flotation due to the buoyancy of oxygen bubbles and magnetotaxis due to the paramagnetic property of oxygen.

Tuning interfacial fluidity and colloidal stability of membranized coacervate protocells

Communications Chemistry
The cell membrane not only serves as the boundary between the cell’s interior and the external environment but also plays a crucial role in regulating fundamental cellular behaviours. Interfacial membranization of membraneless coacervates, formed through
