An embodiment of the present disclosure is a method for forming a substrate. The method includes applying an aqueous solution of nanoparticle precursors to an assembly of fibers, wherein the nanoparticle precursors include a metal salt and a reducing agent. The method also includes drying the assembly of fibers with thermal energy in a continuous operation to form the substrate, thereby drying gives rise to metal nanoparticles in the substrate. The metal nanoparticles have a size that ranges from 1 to about 200 nanometers in at least one dimension.
