摘要: 检测元件的实质是待测靶标的受体,在免疫分析、生物传感器等检测手段中已被广泛运用。目前新型检测元件越来越受到人们的关注,主要包括噬菌体展示多肽、亲和体、纳米抗体和分子印迹聚合物等,这些元件除了亲和力和特异性好,还可以通过直接合成或体外筛选获得,且可以固定于纳米材料表面,因此更利于在传感器中使用。文章概括了上述4种新型检测元件的特性以及其组建的传感器在食品检测领域中的热点应用方向,以期更加广泛地开发利用新型检测元件。

Abstract: Recognition element, known as target receptor, is an important part of sensor since it is responsible for the recognition of target analyte. Sensor with new recognition element has become a powerful tool for the analysis of clinical, environmental, food and commodity samples. New recognition elements, such as phage display peptide, affibody, nanobody and MIPs, can be synthesized in the laboratory or selected in vitro. They have good affinity and specificity, and could be fastened to the surface of nanometer materials, so they can be widely used in sensor. The authors summarized the characteristics of the above 4 kinds of recognition elements and discussed the application in sensors in the food detection to provide reference for the wide development and application of recognition elements.
