“…Detection and selection of such a signal during laser remote sensing of paleoarcheologic places of interest will indicate the areas which should be extensively searched in order to reveal the traces of ancient vegetation (and civilization). Of particular interest is that the same technique can be utilized for life markers detection during extraterrestrial missions on Mars, Venus or Jupiter's moon Europe [33][34][35][36]. It should be noted that fluorescence spectra features transform with time as the organic pigment molecules undergo decomposition.…”

The laser induced fluorescence spectroscopy was systematically utilized for remote sensing of different soils and rocks for the first time, to the best of our knowledge. Laser induced fluorescence spectroscopy measurements were carried out by the developed nanosecond LIDAR instrument with variable excitation wavelength (355, 532 and 1064 nm). LIDAR sensing of different Brazil soil samples have been carried out in order to construct a spectral database. The laser induced fluorescence spectra interpretation for different samples has been discussed in detail. The perspectives of LIDAR sensing of organic samples deposited at soils and rock have been discussed including future space exploration missions in the search for extraterrestrial life.

“…The Raman spectrometer designed for the Martian Moons eXploration (MMX) mission measures only 81 mm × 125 mm × 98 mm and weighs approximately 1.4 kg (Cho et al, 2021). There are other examples in the literature of other miniaturized standoff Raman instruments (Wang et al, 2003;Misra et al, 2016;Abedin et al, 2018;Sandford 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.

“…Based on the unique advantages of Raman spectroscopy, stand-off Raman spectroscopy was initially developed by Angel et al for the detection of K 4 [Fe(CN) 6 ], NaNO 2 , NaNO 3 , and CCl 4 at 17 m in 1992 . After 2000, time-gating techniques and telescopes have been applied in remote detection technology, which greatly enhanced the capability of remote Raman detection. − Until now, the reported farthest distance of remote Raman detection is 1752 m, which used a telescope of 203 mm diameter and a 532 nm pulsed laser for the explosive detection of nitrobenzene, potassium chlorate, and ammonium nitrate . Previously, Bobrovnikov et al reported the trace Raman detection of TNT with a concentration of 0.5 μg/cm 2 from a 10 m distance, which is the lowest concentration that has ever been reported for remote Raman detection of explosives .…”

Remote Raman spectroscopy is a technique that can detect and identify different target molecules through Raman vibrational modes from a remote distance. However, the current remote Raman technique is restricted by poor detection sensitivity, and it is still extremely challenging for trace explosive detection. Here, in order to achieve trace explosive detection from a remote distance, we innovatively propose two enhanced Raman spectroscopy methods by using a plasmonic spray and a laser beam focusing/ Raman signal collecting instrument. In brief, a facile convex lens can converge the laser beam and collect Raman scattering signals, and a plasmonic spray can be used for surface-enhanced Raman scattering. Under the combination of the above enhancement methods, we achieve remote Raman detection of a variety of trace explosives with a concentration of ∼1 μg/cm 2 from a distance of 30 m. These novel methods demonstrate a simple approach that significantly improves the capability of remote detection of trace chemicals for further applications.
