A nanogap of gold distinguishes left and right amino acids electrically. The technique could help in the search for life in space. The article Life in space leaves a molecular fingerprint, this sensor should recognize it first appeared on ingenieur.de - Jobbörse und Nachrichtenportal für Ingenieure.
Amino acids are found in two mirror imagery forms, the ratio of which can provide evidence of biological processes. An electric nanogap sensor distinguishes these L and D forms with more than 80 percent accuracy using artificial intelligence. In samples of the Murchison meteorite and from the Atacama desert, the process also captured the most important patterns of amino acid composition. Osaka (Japan). Many amino acids are chiral and occur in tw…
