Abstract

The search for traces of life is one of the principal aims of Mars exploration. Within the MASE project (Mars Analogues for Space Exploration) we work to improve approaches and methods for biomarker detection and extraction from Mars analogue sites. One promising strategy to study the preservation of biosignatures in Mars conditions consists of the combined study of biomarkers detection and monitoring physicochemical parameters in mineralized samples. We have observed that it there is a correlation between biomarker detection and changes in oxi-reduction potential (ORP) during mineralization process. In addition, these methods and the study of samples from MASE sites have enabled us to develop an antibody microarray for competitive sandwich immunoassays as a potential tool for the detection of biomarkers in salty and anaerobic conditions.
