Mechanical properties of FFP2 masks exposed to NTP generated in Plasmatico v1.0. NTP exposure was performed after insertion of virus or bacteria-free FFP2 masks into Plasmatico v1.0 (exposed for 60, 90 min or 24 h). Mechanical properties were analyzed using tensile test. Left y-axis: Maximal force (N), Right y-axis: Maximal strain (%).
