[MIS17-P10] Supercritical fluids in the search for origins-of-life in Earth and beyond
Keywords:supercritical carbon dioxide, chemical evolution, astrobiology
In this study, we aim to investigate the effect of supercritical carbon dioxide (scCO2) upon chemical reactions that are difficult to occur in aqueous conditions. scCO2 has been known for its use in the industry as a ‘green’ solvent, however it has also found in deep-sea environments in modern ocean and more likely to be present in Hadean Earth which could have served as the key matrix to promote other different chemistry from aqueous chemical reactions. We will focus on two fundamental steps towards the formation of biopolymers 1) Non-enzymatic synthesis of nucleotides (from nucleobase, sugar and phosphate), 2) Condensation of nucleotides and amino acids towards abiotic synthesis of the two-biopolymer architecture.
