In article number 1800826 , Stefan Wuttke, Thomas P. Burg, and co‐workers use a new method, nanomechanical Mass Correlation Spectroscopy (MCS), to reveal an unexpected behavior of the mass density of porous nanoparticles in liquid. The measured mass density is found to depend strongly on the chemical identity of the solvent molecules and on the internal functionalization of the pores. This can be explained by the preferential sorption of different solvent components.
