Electrochemical sensor based on molecularly imprinted polymer coating on metal–organic frameworks for the selective and sensitive determination of carbendazim

Electroanalytical overview: the sensing of carbendazim

“…In order to remove the template molecules, a Soxhlet system with methanol : chloroform mixture (9 : 1 v/v) was used for 48 h. Finally, the HKUST-1@MIP was dried at 40 °C for one hour under vacuum and stored in a desiccator for further use. 48 This sensor displayed a dynamic range of 0.01 to 50 μM with a LOD of 2 nM, and was shown to measure carbendazim within spiked tangerine, tomato, apple and cucumber juices, which was validated against HPLC and showed that the HKUST-1@MIP sensor has practicability and effectiveness in the validation of real samples.

“…41–44 To this end, a variety of MIP sensors have been reported for the sensitive levels of carbendazim. 45–49 Fig. 3A shows how a C-ZIF67@Ni/MIP has been made for the detection of carbendazim from 0.4 pM to 1 nM with a LOD of 0.135 pM.…”

“…A graphite-epoxy electrode has been modified with MIP and a Cu-metal–organic framework. 48 The framework, [Cu 3 (BTC) 2 (H 2 O) 3 ] n (HKUST-1) was synthesized via a solvothermal method. The MIP was formed via polymerisation by adding HKUST-1 with carbendazim and methacrylic acid dissolved within chloroform and was stirred for 60 min.…”

Recent advancements of metal–organic frameworks in sensing platforms: relevance in the welfare of the environment and the medical sciences with regard to cancer and SARS-CoV-2

“…In 2022, Beigmoradi et al designed a MIP-coated MOF-based electrochemical sensor for carbendazim. 55 In this work, HKUST-1 was used as the substrate material, methacrylic acid as the functional monomer and ethylene glycol dimethacrylate as the cross-linker in the presence of a carbendazim template. It is due to the large surface area of HKUST-1 that the sensor has excellent sensing properties.…”

“…Conversely, electrochemical techniques have attracted much attention for measuring MAL and CBZ due to their advantages, such as low detection limits, excellent sensitivity, relative simplicity, reproducibility, portability, low cost, and short sample preparation time. 24,25 Computational chemistry is a subset of chemistry that uses mathematical sciences, statistics, and computer programs to investigate molecular structures, properties, and chemical reactions. 26 This science can help experimental chemistry.…”
