Abstract: The invention is a process useful for providing a treated support comprising a porous nanoweb coating wherein the treated support is characterized by a biofilm cell count of less than 50% that of an untreated porous support control. The process is useful for modifying porous materials, such as filter media and barrier fabrics to provide resistance to biofouling. The porous nanoweb coating is comprised of fibrous structures derived from gelation and drying of supramolecular assemblies of non-covalently bonded organogelators. Typical organogelators useful in the invention include those that assemble via hydrogen bonding and ?-stacking.
