New Membrane Technologies - Nanotube Membranes for Biotechnical Applications

The synthetic membranes in which the molecular recognition chemistry used to accomplish selective permeation are described. These membranes contain template-synthesized gold nanotubes with inside diameters of 12 nanometers, and a "transporter" DNA-hairpin molecule is attached to the inside walls of these nanotubes. These DNA-functionalized nanotube membranes selectively recognize and transport the DNA strand that is complementary to the transporter strand, relative to DNA strands that are not complementary to the transporter.
