Detection of Life on Mars will rely on detection of biomarkers, physical or chemical structures that can be associated with Life. As a possible payload for the ESA ExoMars rover mission planned in 2013 and other future missions a Life Marker Chip instrument is being developed. This instrument uses immuno-assay techniques to detect the relevant biomarkers. This paper describes the typical targets it will search for, its operating principle and the status of development. 63 biomarker targets have been identified and assays have been developed for a limited subset. Assay development includes use of recombinant DNA techniques to generate the molecular receptors (antibodies). This type of instrument has applications in terrestrial research e.g. sub-glacial lakes as well as planetary exploration. Breadboard demonstrators have been built of the assay system and key components of the micro-fluidics. Results from these breadboards will be presented, along with plans for future development.
