Liquid DNA Coacervates form Porous Capsular Hydrogels via Viscoelastic Phase Separation on Microdroplet Interface

open access: yesAdvanced Materials Interfaces
Liquid–liquid phase separation (LLPS) droplets of biopolymers are known as functional microdroplets in living cells and have recently been used to construct protocells and artificial cells.

Compartmentalization and Cell Division through Molecular Discreteness and Crowding in a Catalytic Reaction Network

open access: yesLife, 2014
Explanation of the emergence of primitive cellular structures from a set of chemical reactions is necessary to unveil the origin of life and to experimentally synthesize protocells.

Energy Conversion in Protocells with Natural Nanoconductors [PDF]

open access: yes, 2012
While much nanotechnology leverages solid-state devices, here we present the analysis of designs for hybrid organic-inorganic biomimetic devices, “protocells,” based on assemblies of natural ion channels and ion pumps, “nanoconductors,” incorporated into

Population Dynamics of Autocatalytic Sets in a Compartmentalized Spatial World

open access: yesLife, 2018
Autocatalytic sets are self-sustaining and collectively catalytic chemical reaction networks which are believed to have played an important role in the origin of life.

The RNA-DNA world and the emergence of DNA-encoded heritable traits

open access: yesRNA Biology
The RNA world hypothesis confers a central role to RNA molecules in information encoding and catalysis. Even though evidence in support of this hypothesis has accumulated from both experiments and computational modelling, the transition from an RNA world

Synchronization phenomena in surface-reaction models of protocells [PDF]

open access: yes, 2006
A class of generic models of protocells is introduced,which are inspired by the Los Alamos bug hypothesis but which,due to their abstraction level, can be applied to a wider set ofdetailed protocell hypotheses.

The evolutionary dynamics of metabolic protocells

open access: yesPLOS Computational Biology, 2018
Protocell multilevel selection models have been proposed to study the evolutionary dynamics of vesicles encapsulating a set of replicating, competing and mutating sequences. The frequency of the different sequence types determines protocell survival through a fitness function.

Coming Phase to Phase with Surfactants

open access: yes, 2011
We introduce a fast cellular automata model for the simulation of surfactant dynamics based on a previous model by Ono and Ikegami (2001). Here, individual lipid-like particles undergo stochastic movement and rotation on a two-dimensional lattice in ...

Confocal Microscopy of Diverse Protocells

open access: yes
Modern life is composed of compartmentalization, genetics, metabolism, and self- replication. The precursors to all of this are thought to be protocells, simpler cells that have a lipid membrane with RNA on the inside.

Selection for Motifs Within Protocells: A Computational Study in Prelife

open access: yes, 2019
The transition from pre-life, where self-replication does not occur, to life, where self-replication and Darwinian evolution occur, has not yet been fully delineated.
