Method of producing nanoparticles

Abstract

Disclosed is a method for preparing a nanoparticle composition. The method includes forming a nanoparticle aerosol in a low pressure reactor, wherein the aerosol comprises MX-functional nanoparticles entrained in a gas, where M is an independently selected Group IV element and X is a functional group independently selected from H and a halogen atom. The method further includes collecting the MX-functional nanoparticles of the aerosol in a capture fluid, where the capture fluid is in fluid communication with the low pressure reactor. The capture fluid includes a polar aprotic fluid immiscible with water and having a viscosity of from 5 to 200 centipoise at 25° C. The capture fluid further includes a functionalization compound miscible with the polar aprotic fluid, the functionalization compound comprising a functional group Y reactive with the functional group X of the MX-functional nanoparticles.
