AB  - An octachlorostyrene (OCS) photoelectrochemical (PEC) immunosensor was developed 
      by cross-linking anti-OCS antibody onto a CdTe/CdS-sensitized TiO2 nanotube 
      arrays (NTAs). The anti-OCS polyclonal antibody was developed in rabbit as a 
      result of immunization with BSA-OCS hapten conjugate. TiO2 NTAs were immobilized 
      firstly with hydrothermally synthesized CdTe quantum dots (QDs), and then CdS 
      which filled the spaces within the CdTe-TiO2 composite and encapsulated the CdTe 
      QDs, forming an ideal stepwise bandedge structure, which benefited the light 
      harvesting. The PEC immunosensor therefore shows high specificity and high 
      sensitivity with a limit of detection of 2.58 pM, and a linear range from 5 pM to 
      50 nM. The testing time is 4 min. The analysis of river water reveals that the 
      proposed sensor can be applied in the analysis of OCS in real water samples 
      without complicated pre-treatments.
