“…15,16 More importantly, Apts offer significant flexibility and convenience in their structural design, which has led to Apt-related applications exhibiting high sensitivity and selectivity, and thus Apts have made good progress in the detection of organic molecular contaminants in food analysis. [17][18][19] As an example of an Apt assay of organic contaminants, such as carbendazim, Tang et al 20 used an Aptmediated carbon dot probe for the detection of 2.3 μg L −1 carbendazim in vegetables and fruits. In addition, SERS, RRS, and Abs techniques have been coupled with Apts.…”

Dimethoate contaminants in food pose a threat to human health. Rapid and sensitive trace detection methods are required to keep food safe. In this study, a novel fluorescent aptasensor was developed for the sensitive detection of dimethoate based on carbon quantum dots labeled with double-stranded DNA (CQDs−apt−cDNA) and Ti3C2Tx flakes. Under optimal conditions, the aptasensor showed a good linear range of 1 × 10−9 to 5 × 10−5 M for dimethoate with a coefficient of determination (R2) of 0.996. Besides, a low detection limit of 2.18 × 10−10 M was obtained. The aptasensor showed high selectivity in interference samples and good reproducibility with an RSD of 3.06% (<5%) for dimethoate detection. Furthermore, the proposed aptasensor was applied to the detection of dimethoate in apple juice and tap water with satisfactory recoveries from 96.2 to 104.4%. Because of these benefits, this aptasensor has the potential and promise for detecting food contaminants in the food industry.

“…For now, several analytical measures have been widely adopted for the detection of carbendazim, such as spectroscopic and chromatographic technology, etc. [6][7][8][9] However, these techniques are time-consuming, including the process of separation and determination, and require expensive instruments. Thus, faster and cost-effective alternative approaches, such as electrochemical recognition, should be considered.…”

Pesticide residue is one of the main concerns in human health and environmental safety. A label‐free electrochemical sensor for carbendazim detection based on In2S3 hollow nanotubes is presented. The MOF‐derived In2S3 possessed a porous structure and excellent electrical conductivity properties, leading to the strong affinity to carbendazim pesticide. Under optimized conditions, this sensor exhibited a linear response from 5 to 80 μM and was used to determine carbendazim in the orange juice extract samples, which possesses satisfactory accuracy. Therefore, the method provides broad prospects for rapid and reliable detection of pesticide residues in food and environmental samples.
