“…In recent years, rising concern has been given to the serious problem of pesticide residue in water, which has been causing a strong impact on people's health and the balance of aquatic animals and plants. Cyfluthrin (LC), a type of insecticide, is widely used because of its high efficiency, speed, attacking ability, and so on . However, the residual LC in most rivers has a long‐term and terrible impact on the water environment and water ecological balance according to some investigations .…”

A novel magnetic molecularly imprinted sensor (Fe 3 O 4 /GO/Ag-MIPs) was successfully synthesized. Combining with the technique of surface-enhanced Raman scattering (SERS), it could be applied to detect cyfluthrin (LC). Herein, GO and Ag particles were anchored on the surface of the Fe 3 O 4 @SiO 2 to obtain the composite (Fe 3 O 4 /GO/Ag), which was prepared as a SERS substrate. Then, the Fe 3 O 4 /GO/Ag-MIPs (FGA-MIPs) prepared by precipitation polymerization was evaluated as the SERS imprinted sensor for selective detection of LC from aqueous medium. The morphology and structural properties of FGA-MIPs were characterized by a series of modern analysis measurements. The results proved that FGA-MIPs possessed wonderful magnetic separation, sensitive SERS detection, and selectivity. Under optimal conditions, it exhibited a good linear relationship (R 2 = 0.9926) between the Raman shift (at 1,004 cm −1 ) and the concentration of LC among 10 −3 -10 −8 mol/L, and the limit of detection was 10 −8 mol/L. Meanwhile, the selective experiment indicated that this material owned specific selectivity to the template molecules. Thus, the result of this experiment demonstrated that the FGA-MIPs was a highly sensitive and selective sensor material in the field of LC detection, and it provided a new approach to other residual pyrethroid detection in the environment water.

“…SERS is particularly interesting because of its ultra-sensitive detection mechanism that allows for the detection of analytes in the femtomolar range [ 195 ]. Interesting applications using SERS-based sensors have been developed in recent years mainly focusing on food safety and environmental monitoring [ [196] , [197] , [198] , [199] ].…”

“…Specifically, it is highly challenging to selectively recognize a specific molecule, particularly for low concentrations, from various interference molecular species present in the concerning medium of characterization. Hence, the selective SERS strategy is gaining utmost importance in this current scenario. − …”

The design and synthesis of a highly sensitive and exceptionally selective surface-enhanced Raman scattering (SERS) substrate with an excellent reusable property are of significant interest because of its vast prospective application in actual and complicated detection environments. Here, a simple synthesis strategy was presented to fabricate crystalline two-dimensional (2D) MoO 2 /N-doped-carbon nanosheets with the plasmonic property. The morphology, crystal phase, and surface property of MoO 2 nanomaterials (NMs) were specifically controlled under suitable reaction conditions. In addition, the plasmonic MoO 2 /Ndoped-carbon NM exhibited a SERS maximum enhancement factor up to 1.38 × 10 4 with a detection limit as low as 1.0 × 10 −6 M. More importantly, the as-synthesized nanocomposite shows high selectivity as a "SERS Tweezer" toward methylene blue (MB) in binary and ternary mixed interfering analyte solutions, preserving detection sensitivity toward MB for three cycles via an "elect-and-eliminate" approach. This strategy will be helpful to design other plasmonic semiconductor NMs for successful tangible applications of selective SERS sensing for trace impurity detections in real and complex environments.
