AB  - A photoelectrochemical (PEC) aptasensor based on CdSe@SnS(2) nanocomposite has 
      been developed to detect sulfamethazine (SMZ). The introduction of CdSe into 
      SnS(2) displayed an amplified PEC signal, which was higher than that of pure CdSe 
      and SnS(2), attributable to its enhanced light harvesting capacity and promoted 
      PEC energy conversion efficiency. Due to the formation of specific non-covalent 
      bonds, the SMZ-binding aptamer (SBA) has significant specificity and sensitivity. 
      When SMZ was incubated on a CdSe@SnS(2) modified electrode fixed with aminated 
      SBA, the formation of the SMZ/SBA complex increased the space resistance of 
      electron transfer and hindered the electronic migration between the electrodes, 
      resulting in a decrease in photocurrent. The greater the adsorbed amount on the 
      SBA, the lower the photocurrent produced.  Under optimized conditions the 
      photocurrent response of MCH/SBA/CdSe@SnS(2)/FTO was inversely proportional to 
      the SMZ concentration in the range 0.1 to 100 pM, with a detection limit (3 S/N) 
      of 0.025 pM (at 0 V vs. Hg/HgCl). The recoveries ranged from 95.8 to 104% with 
      relative standard deviations (RSDs) < 6.3% (n = 3) in actual water sample. This 
      PEC aptasensor which shows considerable potential in SMZ detection applications 
      has high selectivity, reproducibility, and good stability.
