High‐aspect‐ratio TiO 2 nanotube (TiNT) layers can be used as low‐cost, low‐volume arrays for fluorescence immunosensing. High sensitivity for antibodies at a concentration of 0.01 pg mL −1 is provided by the high observation length ( L ) of the nanotubes. The photocatalytic properties of TiO 2 make the TiNT arrays reusable after a short UV treatment.
