Laboratory characterization of interplanetary dust particles (IDPs) collected in the lower stratosphere represents a concrete analysis of cosmic dust properties which played a fundamental role in the origin and evolution of Solar System. The IDPs were characterized by Field Emission Scanning Electron Microscope (FESEM) analyses and by InfraRed (IR) micro-spectroscopy. We present the FESEM images of six IDPs: three smooth grains, two porous and one a compact sphere. We also show the results of micro-IR transmission measurements on four IDPs that allowed us to identify their spectral class according to the criteria defined by Sandford and Walker te{sa}. Only three of the analyzed particles show IR transmission spectra with a dominant ``silicate absorption feature'' so that they could be assigned to the three IR spectral classes: one has been classified as ``amorphous olivine'', one appears to be a mixture of ``olivines'' and ``pyroxenes'' and one belongs to the ``layer-lattice silicates'' spectral class.
