This invention discloses a rapid on-site Raman detection method based on acoustic levitation-driven hotspot and molecular co-assembly, comprising the following steps: (1) forming a suspended droplet in a mixed liquid containing the analyte molecule and a nano-substrate in an ultrasonic standing wave sound field; (2) evaporating and concentrating the suspended droplet, and acquiring Raman spectral signals and monitoring the size of the suspended droplet in real time during the evaporation process; (3) determining the optimal value of the enhanced signal based on the real-time correlation between the size change of the suspended droplet and the Raman signal intensity, and realizing trace analysis. This invention enables on-site SERS detection of various toxic and harmful substances with ultra-high sensitivity, good reproducibility, and high detection throughput, significantly improving the performance of surface-enhanced Raman scattering detection.
