description A filtration device containing a porous polyparaxylylene (PPX) filtration article is provided. The PPX filtration article includes at least one PPX polymer membrane layer and one or more substrate. Optionally, the PPX filtration article may include one or more support layer(s). The PPX polymer membrane has a pore size from about 1 nm to about 100 nm. The filtration article has a PVA_20 less than about 0.6 cm3/m2 and/or a mass/area (MPA) less than about 30 g/m2. The PPX filtration article separates and retains nanoparticles from a feed fluid with high permeability. In use, the PPX filtration article filters nanoparticles from a feed flow by passing the feed fluid through at least one PPX polymer membrane within the filtration article where the nanoparticles are separated and removed from the feed fluid. The PPX polymer membranes may be resistant to chemical attack, gamma radiation, and are thermally stable, biocompatible, and strong. 提供一种包含多孔聚对二甲苯(PPX)过滤制品的过滤装置。PPX过滤制品包括至少一个PPX聚合物膜层和一个或多个基材。任选地，PPX过滤制品可以包括一个或多
