Chemical communication in spatially organized protocell colonies and protocell/living cell micro-arrays [PDF]
, 2019 Micro-arrays of discrete or hemifused giant unilamellar lipid vesicles (GUVs) with controllable spatial geometries, lattice dimensions, trapped occupancies and compositions are prepared by acoustic standing wave patterning, and employed as platforms to ...

Triggerable Protocell Capture in Nanoparticle-Caged Coacervate Microdroplets [PDF]
, 2022 Controlling the dynamics of mixed communities of cell-like entities (protocells) provides a step toward the development of higher-order cytomimetic behaviors in artificial cell consortia.

Designing with Protocells: Applications of a Novel Technical Platform
Life, 2014 The paper offers a design perspective on protocell applications and presents original research that characterizes the life-like qualities of the Bütschli dynamic droplet system, as a particular “species” of protocell.

Droplets: Unconventional Protocell Model with Life-Like Dynamics and Room to Grow
Life, 2014 Over the past few decades, several protocell models have been developed that mimic certain essential characteristics of living cells. These protocells tend to be highly reductionist simplifications of living cells with prominent bilayer membrane ...

Engineering coacervate droplets towards the building of multiplex biomimetic protocells
Supramolecular 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 ...

The limits of metabolic heredity in protocells [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2022 The universal core of metabolism could have emerged from thermodynamically favoured prebiotic pathways at the origin of life. Starting with H 2 and CO 2 , the synthesis of amino acids and mixed fatty acids, which self-assemble into protocells, is ...

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

Survival of RNA Replicators Is Much Easier in Protocells Than in Surface-Based, Spatial Systems
Life, 2019 In RNA-World scenarios for the origin of life, replication is catalyzed by polymerase ribozymes. Replicating RNA systems are subject to invasion by non-functional parasitic strands. It is well-known that there are two ways to avoid the destruction of the

Beilstein Journal of Organic Chemistry, 2017 Conceiving the process of biogenesis as the evolutionary development of highly dynamic and integrated protocell populations provides the most appropriate framework to address the difficult problem of how prebiotic chemistry bridged the gap to full ...
