在塞特福德森林,空气采样设备从大气中收集DNA,有望降低食品成本。厄尔汉姆研究所的这项创新技术能比传统方法更快地检测出病原体。这种精确性可以减少农业中的化学品使用,降低成本并有利于环境。
这些以《傲慢与偏见》角色命名的设备每分钟可采集超过200升空气,捕捉来自细菌、病毒和花粉的DNA。对这些DNA进行测序可以揭示当地的生物学特征。
目前这些采样器已在东安格利亚的多个景观中部署,旨在绘制季节性变化图,全面分析预计将于2025年春季完成。博士后科学家达伦·海沃斯预测,随着农民根据空气传播的病原体检测采用更有针对性的化学品应用,食品价格将会下降。
尽管这项研究尚处于起步阶段,但它有可能重新定义农业和公共卫生策略,使其更加高效和经济。
