Engineering Polymersome Protocells [PDF]

open access: yesThe Journal of Physical Chemistry Letters, 2011
The field of biomimicry is embracing the construction of complex assemblies that imitate both biological structure and function. Advancements in the design of these mimetics have generated a growing vision for creating an artificial or proto- cell. Polymersomes are vesicles that can be made from synthetic, biological or hybrid polymers and can be used ...

Progress in synthesizing protocells [PDF]

open access: yesExperimental Biology and Medicine, 2018
The traditional route to investigating biology by perturbing living systems or by individually purifying and characterizing component parts is giving way to more complex endeavors where chemists and physicists attempt to build cells from scratch. Parallel efforts are underway that either exploits extant biological parts or prebiotically plausible ...

Introduction. Artificial protocells [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2007
What makes a cell? How are cells able to replicate themselves in a stable manner? How did cellular life emerge on our planet? The answer to these fundamental questions lies at the base of biology.

Engineering coacervate droplets towards the building of multiplex biomimetic protocells

open access: yesSupramolecular Materials, 2022
The origin of life on Earth remains one of the biggest open questions in science. Despite recent advances in molecular mechanism of cell biology, a large blind spot still exists between non-living matter and the emergence of life which cannot be filled ...

Effect of migration in a diffusion model for template coexistence in protocells [PDF]

open access: yes, 2014
The compartmentalization of distinct templates in protocells and the exchange of templates between them (migration) are key elements of a modern scenario for prebiotic evolution.

A stochastic model of catalytic reaction networks in protocells [PDF]

open access: yes, 2014
Protocells are supposed to have played a key role in the self-organizing processes leading to the emergence of life. Existing models either (i) describe protocell architecture and dynamics, given the existence of sets of collectively self-replicating ...

Fatty Acid Vesicles as Hard UV-C Shields for Early Life

open access: yesFoundations, 2023
Theories on life’s origin generally acknowledge the advantage of a semi-permeable vesicle (protocell) for enhancing the chemical reaction–diffusion processes involved in abiogenesis.

Nonreplicating Protocells

open access: yesAccounts of Chemical Research, 2012
Prebiotic soup experiments have shown that the molecular building blocks of life can be built under prebiotically plausible conditions. From this starting point, researchers have launched continued studies of polymerization and explorations of the breadth of RNA function.

The origin of heredity in protocells [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2017
Here we develop a computational model that examines one of the first major biological innovations—the origin of heredity in simple protocells. The model assumes that the earliest protocells were autotrophic, producing organic matter from CO 2 and H 2 .

Selfishness versus functional cooperation in a stochastic protocell model [PDF]

open access: yes, 2010
How to design an "evolvable" artificial system capable to increase in complexity? Although Darwin's theory of evolution by natural selection obviously offers a firm foundation, little hope of success seems to be expected from the explanatory adequacy of ...
