With the increasing development of the society and the growing awareness to health, the public has been concerned about the safety and quality of agriculture and food products for many years. Biosensor, an efficient analytical device, has been broadly applied in the analysis to agriculture and food samples. Since the analytes in agriculture and food samples are low-abundant and complex, there is an urgent need to concentrate the analytes with suitable enrichment methods before the biosensor-based detection. In this review, we highlight recent advances and future trends in the biosensor-integrated enrichment methods to preconcentrate the low-abundant analytes of agriculture and food samples, including material-based enrichment methods and electric-based enrichment methods. We do hope that the biosensor-integrated enrichment methods would be easier, more stable, novel, integrated and efficient in the next few years and the enrichment performance would be enhanced with the inspirations from our review.

随着社会的发展和健康意识的增强，多年来人们一直关注农业和食品的安全和质量。生物传感器是一种有效的分析设备，已广泛应用于农业和食品样品的分析中。由于农业和食品样品中的分析物含量低且复杂，因此迫切需要在基于生物传感器的检测之前使用合适的富集方法浓缩分析物。在这篇综述中，我们重点介绍了生物传感器集成的富集方法的最新进展和未来趋势，以预浓缩农业和食品样品的低丰度分析物，包括基于材料的富集方法和基于电子的富集方法。我们确实希望将生物传感器集成的富集方法变得更容易，
