AB  - A new and signal-off photoelectrochemical (PEC) sensing platform utilizing TiO(2) 
      nanotube arrays (NTAs) coated with Bi(2)WO(6) nanoparticles (NPs) has been 
      successfully developed for the highly sensitive detection of sunset yellow (SY). 
      The interaction between SY and Bi(2)WO(6) NPs leads to substantial steric 
      hindrance, resulting in a noticeable decrease in the photocurrent signal. The 
      proposed PEC sensor demonstrates quantitative detection capabilities for SY 
      across a wide liner range of 10 fM to 100 microM with an ultralow detection limit 
      (LOD) of 0.78 fM. Furthermore, the designed PEC sensor exhibits several notable 
      advantages, including robust anti-interference properties, desirable 
      repeatability, good reproducibility, and excellent stability. Finally, the 
      designed PEC sensor was applied to determine SY in diverse real samples without 
      any remarkable difference compared to the UV-Vis reference method.
