Can prebiotic systems survive in the wild? An interference chemistry approach

Frontiers in Earth Science, 2022
It is challenging to evaluate the relevance of any given chemical system or geological environment to the origin of life. At the same time, life is the product of prebiotic chemistry that took place in some environment.

Plasma Modeling and Prebiotic Chemistry: A Review of the State-of-the-Art and Perspectives. [PDF]

Molecules, 2021
We review the recent progress in the modeling of plasmas or ionized gases, with compositions compatible with that of primordial atmospheres. The plasma kinetics involves elementary processes by which free electrons ultimately activate weakly reactive ...

From gaseous HCN to nucleobases at the cosmic silicate dust surface: an experimental insight into the onset of prebiotic chemistry in space

Physical Chemistry, Chemical Physics - PCCP, 2022
HCN in the gas form is considered as a primary nitrogen source for the synthesis of prebiotic molecules in extraterrestrial environments. Nevertheless, the research mainly focused on the reactivity of HCN and its derivatives in aqueous systems, often ...

The Prebiotic Kitchen: A Guide to Composing Prebiotic Soup Recipes to Test Origins of Life Hypotheses

Life, 2021
“Prebiotic soup” often features in discussions of origins of life research, both as a theoretical concept when discussing abiological pathways to modern biochemical building blocks and, more recently, as a feedstock in prebiotic chemistry experiments ...

Nanoscale Anatomy of Iron-Silica Self-Organized Membranes: Implications for Prebiotic Chemistry. [PDF]

Angew Chem Int Ed Engl, 2021
Iron‐silica self‐organized membranes, so‐called chemical gardens, behave as fuel cells and catalyze the formation of amino/carboxylic acids and RNA nucleobases from organics that were available on early Earth.
