Abstract: In recent years, it has become important to identify phenols and their compounds that pose an important threat to living things and public health. In this study, phenol imprinted surface plasmon resonance (SPR) sensors were designed based on molecular imprinted method for detection of phenol. Polymeric film with cavities of phenol molecules was prepared and formed on the SPR chip surface by UV polymerization. The limit of detection range from 0.15 to 10 nM was 0.022 nM. Furthermore, we performed the selectivity experiments, where catechol was chosen as competitor agent. Overall, phenol imprinted SPR sensor prepared by the molecular imprinting approach has been found to be highly sensitive and selective for phenol. Phenol imprinted SPR sensors are considered to be used as a new method for existing phenol determination methods with their high selectivity, repetitive use and fast responses.
