Biochip for astrobiological applications: Investigation of low energy protons effects on antibody performances

► Resistance under low energy protons (2 MeV) of antibody-based micro-arrays instruments. ► Antibodies were irradiated under three freeze-dried conditions. ► No proton irradiation effect were observed. ► Need to encompass all the constraints encountered during a planetary mission. ► Further experiments will be performed using International space station facilities.
