1. A membrane comprising:
a matrix having a first surface and an opposed second surface, wherein the matrix is at least one of a polymeric matrix or an inorganic matrix; and
a plurality of substantially vertically aligned boron-nitride nanoparticles disposed in the matrix, wherein each of the plurality of substantially vertically aligned boron-nitride nanotubes extends beyond at least one of the first surface of the matrix and the second surface of the matrix, wherein each of the plurality of boron-nitride nanotubes includes a first end exposed and opened by etching at the first surface of the matrix and a second end exposed and opened by etching at the second surface of the matrix, and an inner hollow diameter configured for selective molecular transport from the first surface of the matrix to the second surface of the matrix.
