Solution plasma synthesis of α-amino acids

Abstract

Over 70 years after the Miller–Urey experiment, synthesizing amino acids from inorganic molecules still faces low selectivity and poor yield. This study uses solution plasma to synthesize amino acids from CH₄–NH₃–H₂, achieving a yield of 341.0 μg L⁻¹ and a serine-to-glycine ratio of 144.5%, the highest reported for clean synthesis.
