Abstract

Multi-component particles comprising inorganic nanoparticles distributed in an organic matrix and processes for making and using same. A flowing aerosol is generated that includes droplets of a precursor medium dispersed in a gas phase. The precursor medium contains a liquid vehicle and at least one precursor. At least a portion of the liquid vehicle is removed from the droplets of precursor medium under conditions effective to convert the precursor to the nanoparticles or the matrix and form the multi-component particles.
