Abstract: Mass spectrometry (MS) and adsorption on the surface of a single nanoparticle (NP) are combined in a cryogenic ion trap. This opens new paths such as action spectroscopy for characterizing intrinsic properties of single NPs without ensemble broadening or surface interactions. Recent progress on fluorescence thermometry with CdSe/CdS quantum dots and measuring the argon binding energy from adsorption curves on a silica NP pave the way for MS-mediated temperature-programmed desorption approaches.
