　　The strong interactions of metal nanoparticle localized surface plasmon resonances (LSPR) with their immediate environment have applications in fields ranging from catalysis to medicine.Understanding how the particles size, shape and surroundings modulate the LSPR interactions is essential to optimizing them for a given application [1,2].Electron energy-loss spectroscopy (EELS), using a monochromated electron source in a scanning transmission electron microscope (STEM), has previously been successfully employed to detect the dark modes and weak dipoles of LSPR with high spatial and energy resolution.However, changes in the LSPR of metal nanoparticles during gas exposure are unexplored.
