Abstract

Microbially contaminated food can cause serious health hazards and economic losses, therefore sensitive, rapid, and highly specific visual detection is called for. Traditional detection of microorganisms is complex and time-consuming, which cannot meet current testing demands. The emergence of paper-based biosensors provided an effective method for efficient and visual detection of microorganisms, due to its high speed, all-in-one device, low cost, and convenience. This review focused on 5 biomarkers, namely nucleic acids, proteins, lipopolysaccharides, metabolites, and the whole microorganism of microorganisms. Besides, the recognition methods were summed up in 5 forms, including immunological recognition, aptamer recognition, nucleic acid amplification-mediated recognition, DNAzyme recognition and clustered regularly interspaced short palindromic repeats mediated recognition. In addition, we summarized the applications of paper-based biosensors in the detection of microorganisms thoroughly. Through the exploration of different biomarkers, identification methods, and applications, we hope to provide a reference for the development of paper-based biosensors and their application in safeguarding the food chain.

基于多种识别模式的纸质生物传感器对微生物污染食品的视觉检测
受微生物污染的食品会造成严重的健康危害和经济损失,因此需要灵敏、快速、特异性强的视觉检测。传统的微生物检测既复杂又耗时,无法满足当前的检测需求。纸基生物传感器的出现提供了一种高效、直观地检测微生物的有效方法,因为它具有高速、一体式设备、低成本和方便性。综述了5种生物标志物,即核酸、蛋白质、脂多糖、代谢产物和微生物的整个微生物。此外,将识别方法归纳为5种形式,包括免疫识别、适体识别、核酸扩增介导的识别、DNA酶识别和聚类规则间隔短回文重复序列介导的辨识。此外,我们还全面总结了纸基生物传感器在微生物检测中的应用。通过对不同生物标志物、识别方法和应用的探索,我们希望为纸基生物传感器的发展及其在保障食物链中的应用提供参考。
