Extraterrestrial prebiotic molecules: photochemistry vs. radiation chemistry of interstellar ices [PDF]
, 2019 In 2016, unambiguous evidence for the presence of the amino acid glycine, an important prebiotic molecule, was deduced based on in situ mass-spectral studies of the coma surrounding cometary ice.

Harnessing prebiotic formamide chemistry: a novel platform for antiviral exploration
Scientific ReportsViruses and host cells are intricately connected through a shared “chemical language” that may trace back to the prebiotic chemistry of early Earth. In this study, we present an innovative platform for antiviral exploration inspired by this primordial ...

Can synthetic biology shed light on the origin of life? [PDF]
, 2009 It is a most commonly accepted hypothesis that life originated from inanimate matter, somehow being a synthetic product of organic aggregates, and as such, a result of some sort of prebiotic synthetic biology.
