“…A SCE procedure and a chromatographic separation/detection method were developed for the detection of earth-based microorganisms. The analytical results demonstrated the feasibility of using the reported techniques to detect the chemical signature of life in barren desert sand samples (Lang et al, 2002). Another interesting application of SCF in biotechnology is detecting the presence of a microorganism in an environmental sample.…”

“…The experiments need to be repeated, with modifications based on all we have learned in the succeeding years. There are now improved ways to monitor microbial signatures and metabolic processes that are indicative of life in soil [35-37]. The fact that spores appear to survive for many decades and perhaps hundreds of millions of years in earthly systems further supports the possibility for survival of similar life forms on Mars.…”

Background: Martian soil is thought to be enriched with strong oxidants such as peroxides and/ or iron in high oxidation states that might destroy biological materials. There is also a high flux of ultraviolet radiation at the surface of Mars. Thus, Mars may be inhospitable to life as we know it on Earth. We examined the hypothesis that if the soil of Mars contains ferrates [Fe(VI)], the strongest of the proposed oxidizing species, and also is exposed to high fluxes of UV radiation, it will be selfsterilizing.

“…Furthermore, the Martian atmosphere contains 95% CO 2 , which could potentially be harvested for SFE applications that use neat scCO 2 . It has also been proposed that dry ice in the polar regions of Mars could be utilized as a natural extraction solvent for in situ SFE (Lang et al, 2002). SFE, in parallel with SCWE, followed by supercritical fluid chromatography (SFC) and LC with mass spectrometry detection, are utilized in the Supercritical CO 2 and Subcritical H 2 O Analysis instrument (SCHAN; Lin et al, 2021).…”

The search for life in Solar System bodies such as Mars and Ocean Worlds (e.g., Europa and Enceladus) is an ongoing and high-priority endeavor in space science, even ∼ five decades after the first life detection mission at Mars performed by the twin Viking landers. However, the in situ detection of biosignatures remains highly challenging, both scientifically and technically. New instruments are being developed for detecting extinct or extant life on Mars and Ocean Worlds due to new technology and fabrication techniques. These instruments are becoming increasingly capable of both detecting and identifying in situ organic biosignatures that are indicative of life and will play a pivotal role in the search for evidence of life through robotic lander missions. This review article gives an overview of techniques used for space missions (gas chromatography, mass spectrometry, and spectroscopy), the further ongoing developments of these techniques, and ion mobility spectrometry. In addition, current developments of techniques used in the next-generation instruments for organic biosignature detection are reviewed; these include capillary electrophoresis, liquid chromatography, biosensors (primarily immunoassays), and nanopore sensing; whereas microscopy, biological assays, and isotope analysis are beyond the scope of this paper and are not covered.
