中文摘要：本研究用铝基金属有机框架(MOFs)制作了两种独特的免疫传感器，命名为515-和516-MOFs，具有4,4',4''-三甲酸三苯胺（NTB）= H3NTB，能有效地用于食品安全评估。研究表明，这种新方法灵敏度高、选择性好且操作简单，在简易检测食品有毒有害残留物方面潜力巨大。
外文摘要：Two unique immunosensors made of aluminum-based metal-organic frameworks (MOFs), namely, 515- and 516-MOFs, with 4,4',4''-nitrilotribenzoic acid (NTB) = H3NTB were successfully obtained to efficiently assess food safety. The as-prepared 515- and 516-MOFs exhibited superior thermal and physicochemical stability, high electrochemical activity, and good biocompatibility. Among these immunosensors, 516-MOF showed a preferable biosensing ability toward analytes determined by electrochemical techniques. The developed 516-MOF-based electrochemical biosensor not only demonstrated high sensitivity with low detection limits of 0.70 and 0.40 pg mL/1 toward vomitoxin and salbutamol, respectively, but also showed good selectivity in the presence of other interferences. Therefore, with the advantages of high sensitivity, good selectivity, and simple operation, this new strategy is believed to exhibit great potential for simple and convenient detection of poisonous and harmful residues in food.
