天体生物学研究的一个关键问题是识别具有明确生物起源并且可以轻松检测和识别的目标分子。我们建议卟啉衍生物作为一个理想的目标，因为这些生色团是全球性的分布，并发现在地球上几乎所有的生物体，包括微生物，可能近似地球上生命的早期进化。我们讨论的内在品质，使卟啉非常适合天体生物学的研究，并讨论在陆地沉积环境中检测卟啉分子的方法。我们提出了初步的数据，以支持使用ToFSIMS作为一个强大的技术，在卟啉的鉴定。
A key issue in astrobiological research is identifying target molecules that are unambiguously biological in origin and can be easily detected and recognized. We suggest porphyrin derivatives as an ideal target, because these chromophores are global in distribution and found in virtually all living organisms on Earth, including microorganisms that may approximate the early evolution of life on Earth. We discuss the inherent qualities that make porphyrin ideally suited for astrobiological research and discuss methods for detecting porphyrin molecules in terrestrial sedimentary environments. We present preliminary data to support the use of ToFSIMS as a powerful technique in the identification of porphyrins.
