The highly sensitive technique of microchip capillary electrophoresis (μCE) with laser-induced fluorescence (LIF) detection is under development for future in situ spaceflight missions to search for the organic chemical signatures of life. One fluorescent probe that enables this technology for amine, amino acid, and dipeptide analysis is 3-carboxy-6,8-difluoro-7-hydroxycoumarin (Pacific Blue™, PB)...
The search for signs of life on extraterrestrial planetary bodies is among NASA's top priorities in Solar System exploration. The associated pursuit of organics and biomolecules as evidence of past or present life demands in situ investigations of planetary bodies for which sample return missions are neither practical nor affordable. These in situ studies require instrumentation capable of sensitive...
