The variety of properties of highly dispersed (nano) materials made them promising for use in inorganic analysis, including atomic spectrometry (atomic absorption spectrometry, atomic emission and mass spectrometry with inductively coupled plasma). These materials are used as solid-­phase extractants and matrix modifiers, and are also the object of analysis. The article discusses ways to obtain and characterize nanoparticles; provides data on the structure and properties of magnetic nanoparticles, intended for solving analytical and biomedical problems; shows the possibility of increasing the sensitivity and selectivity of the determination of a number of elements using nanoparticles in atomic absorption spectrometry with electrothermal atomization and in the cold vapor technique. The new possibilities of spectrometric methods for bioanalytical applications involving nanopar­ticles, including inductively coupled plasma mass spectrometry in the single particle mode, are analyzed.
