Claim 13:
14. A method of fabricating a nanoporous membrane of claim 1, comprising:
a. providing a solution of polymeric micelles by dissolving amphiphilic copolymers in an organic solvent;
b. obtaining a two-layer film by coating onto a porous support layer the solution of polymeric micelles to form a selective layer that contains an array of polymeric nanoparticles and nanopores therebetween, wherein the polymeric nanoparticles each having on their surfaces a plurality of —C(═O)OH groups; and
c. transforming the plurality of —C(═O)OH groups in part or in whole to a plurality of —C(═O)XR groups.
