Fluorescent nanotubes are fabricated by layer‐by‐layer deposition of oppositely charged core–shell macromolecules on the template of a nanoporous membrane. These nanotubes contain either positively or negatively charged surfaces and are exploited as specific functional substrates for dual‐responsive DNA probing and targeting. The nanotube (red)/DNA (blue) complex is visualized as a dual‐color nanotube in double‐ fluorescence imaging.
