1. A process, comprising the steps of:
aerosolizing one or more particles into suspension within a gas, each of the one or more particles comprising functionalized nanoparticles having an electric charge;
attracting the one or more particles onto a substrate by a static electric charge opposite of the electric charge, at least portions of the substrate having the static electric charge, the substrate being porous and non-conductive; and
depositing the functionalized nanoparticles onto the substrate.
