    摘要:

    氟喹诺酮类药物(FQs)通常用于预防和治疗畜产养殖、水产养殖过程中的动物疾病,然而过量或不规范使用等会产生耐药菌株,而含FQs残留的动物性食品进入食物链会导致人体生物蓄积毒性。探索FQs有效的检测方法逐渐成为众多学者的关注点。目前国内外建立了多种检测FQs的方法。基于核酸适配体的氟喹诺酮类兽药检测方法相比于其它方法具有灵敏度高、特异性好、成本低、快速等优点。本文概述近5年国内外核酸适配体生物传感器检测FQs的研究进展,主要从荧光、比色和电化学等模式阐述各类检测传感器方法的原理、技术应用及优缺点,指出目前检测方法存在的问题,展望未来生物传感检测技术的发展方向。

    Abstract:

    Fluoroquinolones(FQs) are usually used to prevent and treat animal diseases in livestock and aquaculture. However, excessive or irregular use of FQs can cause the production of drug-resistant strains. Moreover, the introduction of animal foodstuff with FQs residues into food chain can lead to bioaccumulative toxicity. Therefore, to explore the effective FQs detection methods has gradually become the focus of many researchers. At present, various detection methods have been established at home and abroad. The aptamer-based methods for FQs detection compared with other methods, especially, have the advantages of high sensitivity, good specificity, low cost and rapid operation. Therefore, the research progress of the worldwide aptamer-based biosensors used in FQs detection in the late five years was summarized in this review. The principle, technical application, advantages and disadvantages of diverse FQs aptamer biosensors were described in detail, covering fluorescent, colorimetric and electrochemical and other sensors. Finally, the problems existing in detection methods were discussed, and an outlook for development direction of aptamer-based FQs detection biosensors in the future was made in the review.
