The method includes: dispersing an active bind› ing agent in an organic solvent solution to create a suspen› sion of the active binding agent and the solution of the  solvent; dissolving an organic polymer resin and an anionic  surfactant in the suspension of the active binding agent and  the solvent solution to create a sol gel; and electrospinning  the sol gel to form electrospun nanofiber composites with  embedded, surface-active nanoparticles.
