Novel study of 3 − Monochloropropane−1,2 − diol detection on amine − terminated boron-doped diamond nanoparticles

The 3 − monochloropropane−1,2 − diol (3 − MCPD) is a widely recognized contaminant that typically forms during the high-temperature processing of food, such as in the production of palm oil. This compound has been shown to exhibit toxicity, particularly in the kidneys and testes, and possesses non-genotoxic carcinogenic properties that may contribute to cancer development. In this study, we introduce a highly sensitive and selective electrode for the detection of 3 − MCPD, based on amine-terminated boron-doped diamond nanoparticles integrated onto a screen-printed electrode (N − BDDNP/SPE). The formation of N − BDDNP was thoroughly characterized using scanning electron microscopy (SEM), energy-dispersive X − ray spectroscopy (EDX), and Raman spectroscopy. The developed electrode demonstrated an impressively low limit of detection (LOD) of 0.034 μM, alongside remarkable sensitivity and selectivity, making it suitable for the detection of 3-MCPD in various real-world samples. Thus, this fabricated electrode holds significant potential for applications in quality assurance and control within the oil industry.
