1. A method of forming a filter with uniform pore sizes, comprising:
- synthesizing a moiety so as to form a plurality of platelets having a precisely sized pore extending therethrough;
distributing said plurality of platelets about a membrane, said membrane having apertures therethrough; and
bonding said plurality of platelets around said apertures to form precisely sized pores through said membrane,wherein the platelets comprise a combination of aryl rings.

Abstract
A method of forming a filter with uniform pore sizes includes synthesizing a moiety so as to form a plurality of like platelets having a precisely sized pore extending therethrough, distributing the plurality of like platelets about a membrane having apertures therethrough, and bonding the plurality of platelets around the apertures to form precisely sized pores through the membrane. A filtration membrane is also disclosed which provides a porous membrane having a plurality of apertures therethrough, and a plurality of platelets, wherein each platelet has a pore therethrough. The platelets are positioned over or in the apertures.
