International audience; Future long-duration human spaceflight calls for developments to limit biocontamination of the surface habitats. The MATISS experiment tests surface treatments in the ISS's atmosphere. Four sample holders were mounted with glass lamella with hydrophobic coatings, and exposed in the Columbus module for~6 months. About 7800 particles were detected by tile scanning optical microscopy (×3 and ×30 magnification) indicating a relatively clean environment (a few particles per mm 2), but leading to a significant coverage-rate (>2% in 20 years). Varied shapes were displayed in the coarse (50-1500 µm 2) and fine (0.5-50 µm 2) area fractions, consistent with scale dices (tissue or skin) and microbial cells, respectively. The 200-900 µm 2 fraction of the coarse particles was systematically higher on FDTS and SiOCH than on Parylene, while the opposite was observed for the
