TiO2 Nano Test Tubes as a Self-Cleaning Platform for High-Sensitivity Immunoassays

High‐aspect‐ratio TiO2 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 TiO2 make the...

Zusammenfassung:	High‐aspect‐ratio TiO2 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 TiO2 make the TiNT arrays reusable after a short UV treatment.
