The quality and safety of food and agro-product is closely aligned with the development of human society. In the process of production, transportation and storage, the detection of indexes is indispensable to ensure the quality and safety of food and agro-product. The conventional detection methods such as using chromatography instruments and bacterial colony are expensive and complex. Hence, in recent years, CNTs-based sensors for food and agro-product detection are of growing interest. Compared to the conventional detection methods, CNT-based sensors display remarkable stability, superior mechanical, excellent thermal conductivity, optical and electronic performance, high antibacterial properties and chemical stability which enable the quality detection to be faster, cheaper and more accurate. Here, we comprehensively review the recent advances in those sensors for food quality detection, including the detection of fruit ripeness, ingredients, pesticides, noxious substances and allergens. We hold the view that the applications of CNTs in detection can be divided into two categories. One is to use CNTs and their composite materials as adsorption fillers in different sample pretreatment technologies. The other is to use them to modify electrodes and fix biological recognition elements. Furthermore, the current challenges and prospects in this field are included here to provide an overview of future research directions. [ABSTRACT FROM AUTHOR] |
