AB  - In this paper, tris(2,3-dibromopropyl) isocyanurate (TBC) is for the first time 
      as far as we know determined by ultrasensitive photoelectrochemical (PEC) 
      immunoassay using an antibody-modified ternary hybrid CdTe/Au-TiO2 nanotube 
      arrays (NTAs) photoelectrode, developed by the pulse electrodeposition technique. 
      The as-prepared hybrid shows enhanced photon absorption and photocurrent 
      response, which subsequently increased the photoelectrical conversion efficiency 
      in the visible region. TBC-antibody (Ab) was developed in rabbits as a result of 
      immunization with the BSA-TBC conjugate and covalently cross-linked onto the 
      CdTe/Au-TiO2 NTAs. Since the photocurrent is highly dependent on the TiO2 surface 
      properties, the specific interaction between TBC and the antibody results in a 
      sensitive change in the photocurrent, which displayed a linear range of 5.0 x 
      10(-11) to 5.0 x 10(-5) M and a low detection limit of 5.0 x 10(-11) M for TBC 
      determination. This proposed strategy highlights the application of TiO2 nanotube 
      in visible-light-activated photoelectrochemical biosensing, which could largely 
      reduce the destructive effect of UV light on biomolecules.
