“…AChE hNFs/Au NPs/GO/glassy carbon electrode showed favorable detection performance due to the AChE hNFs have large surface area and provide the affinity to substrates with improved catalytic activity (Figure 2B). This biosensor enabled the determination of dichlorvos with a detection limit of 0.07 pM and exhibited great detection accuracy and recoveries about 98.65%–103.43% in real agricultural samples 56 . In another study, the same researchers reported the fabrication of in situ growth of aptamer (Apt) based AChE hNFs.…”

In recent years, an encouraging breakthrough in the synthesis of immobilized enzymes in flower‐shaped called “organic‐inorganic hybrid nanoflowers (hNFs)” with greatly enhanced catalytic activity and stability were reported. Although, these hNFs were discovered by accident, the enzymes exhibited highly enhanced catalytic activities and stabilities in the hNFs compared with the free and conventionally immobilized enzymes. Herein, we rationally utilized the catalytic activity of the hNFs for analytical applications. In this comprehensive review, we covered the design and use of the hNFs as novel versatile sensors for electrochemical, colorimetric/optical and immunosensors‐based detection strategies in analytical perspective.

“…However, most organophosphorus do not have inherent redox activity. In order to detect organophosphorus without inherent redox activity, electrochemical sensors use the inhibition of organophosphorus on enzyme activity to detect organophosphorus pesticides [11][12][13]. However, complex detection conditions, including the temperature, pH value, and solvent type, will affect the detection activity of the enzymes.…”

In this work, a flexible electrochemical sensor was developed for the detection of organophosphorus pesticides (OPs). To fabricate the sensor, graphene was generated in situ by laser-induced graphene (LIG) technology on a flexible substrate of polyimide (PI) film to form a three-electrode array, and pralidoxime (PAM) chloride was used as the probe molecule. CeO2 was used to modify the working electrode to improve the sensitivity of the sensor because of its electrocatalytic effect on the oxidation of PAM, and the Ag/AgCl reference electrode was prepared by the drop coating method. The effects of the laser power, laser scanning speed, and CeO2 modification on the electrochemical properties of the sensor were studied in detail. The results prove that the sensor has good repeatability, stability, and anti-interference ability, and it shows an excellent linear response in the chlorpyrifos concentration range from 1.4 × 10−8 M to 1.12 × 10−7 M with the detection limit of 7.01 × 10−10 M.
