Abstract
Present study details the expansion of a sensing platform based on magnetic imprinted layer system for plant pigment. A scalable, simple, cost-effective and novel magnetic imprinted layer constructed of Fe3O4@polyaniline/reduce graphene oxide molecular imprinted membrane (M@PANI/rGO MIP) was manufactured on the surface of the magnetic carbon paste electrode (MCPE). The prepared M@PANI/rGO MIP was investigated with all the significant physical characteristics including composition, topography and morphology. The synthesized M@PANI/rGO MIP was displayed stability and exceptional electrochemical activity due to presenting tailor-made receptors. Upon the electrochemical investigation, a sensitive MIP sensing platform for the detection of rutin led to two linear calibration curves in the range of 0.01–1 pM and 0.00001–10 µM and an ultralow detection limit (0.356 fM). Consequently, the proposed MIP platform evidently was featured accurate detection of rutin in fruits and could be recommended for real-time analysis.
