The 100 nm hematite Fe2O3 particles in gelatin gel, dense water solution of sugar, commercial paints, foam, cosmetic cream and friable powder exhibit the mobility in the range of mm/s which was determined from the analysis of the resonance absorption line shape. In the solution of sugar the movement is correlated for particle–particle distance less then 300 nm. The Mössbauer spectroscopy of the iron bearing nanoparticles is proposed as a novel experimental technique for the investigation of the dynamical and structural properties of the soft matter at the mesoscoipic scale.
