New Aptamer/MoS(2)/Ni-Fe LDH Photoelectric Sensor for Bisphenol A Determination
Here, a new type of PEC aptamer sensor for bisphenol A (BPA) detection was developed, in which visible-light active MoS(2)/Ni-Fe LDH (layered double hydroxide) heterostructure and aptamer were used as photosensitive materials and biometric elements, respectively. The combination of an appropriate am...

description | Here, a new type of PEC aptamer sensor for bisphenol A (BPA) detection was developed, in which visible-light active MoS(2)/Ni-Fe LDH (layered double hydroxide) heterostructure and aptamer were used as photosensitive materials and biometric elements, respectively. The combination of an appropriate amount of MoS(2) and Ni-Fe LDH enhances the photocurrent response, thereby promoting the construction of the PEC sensor. Therefore, we used a simple in situ growth method to fabricate a MoS(2)/Ni-Fe LDH sensor to detect the BPA content. The aptasensor based on aptamer/MoS(2)/Ni-Fe LDH displayed a linear range toward a BPA of 0.05–10 to 50–40,000 ng L(−1), and it has excellent stability, selectivity and reproducibility. In addition, the proposed aptamer sensor is effective in evaluating real water samples, indicating that it has great potential for detecting BPA in real samples. |
