- Abstract:
- This study concerns the design of an electrochemical sensor functionalized with a polypyrrole-molecularly imprinted polymer (PPy- MIP) for bisphenol A (BPA) detection. Here, N, N'- methylene-bis-acrylamide was chosen as the chelating agent due to its accessible carbonyl and amine groups. Extraction of BPA templates from the vicinity of the PPy-polymeric matrix was optimized by electrochemistry and Fourier Transform Infrared spectroscopy (FTIR). The limit of detection of the designed sensor was of order of 1 nM and the sensitivity was equal to (9.66 ± 0.86) µA/M respectively. The dissociation constant Kd, which provides information on the affinity between the templates and the cavities, was estimated from a combined one-site binding - Hill model. Kd was of order of (2.05 ± 0.18) 10-9 M.
