通用纳米传感器揭开植物生长的奥秘Universal nanosensor unlocks the secrets to plant growth
➀ 新加坡-麻省理工学院科研团队（DiSTAP）研发出首款近红外荧光纳米传感器，可实时、无损检测植物生长素（IAA），精准监测植物发育和抗逆反应；
➁ 该传感器无需基因改造，可跨物种使用，规避叶绿素干扰，并与农业系统集成以优化灌溉、施肥，提升作物产量；
➂ 未来将结合多传感器实现激素信号全景分析，并与都市农场合作推动技术落地，助力精准农业和可持续发展。
➀ Researchers from DiSTAP developed the first near-infrared fluorescent nanosensor for real-time, non-destructive detection of auxin hormone (IAA) in plants, enabling precise monitoring of growth and stress responses;
➁ The sensor bypasses chlorophyll interference, works across plant species without genetic modification, and integrates with agricultural systems to optimize irrigation, nutrient delivery, and crop yields;
➂ Future plans include combining sensors for comprehensive hormone profiling and collaborating with urban farms to translate the technology into practical solutions.
