AB  - The environmental pollution and human health risks caused by anti-infective 
      residual drugs in the environment have attracted much attention. More convenient 
      and effective detection methods to achieve the rapid and high sensitivity 
      detection for such pollutants are required. In this work, a novel 
      surface-enhanced Raman scattering (SERS) strategy based on vortex aggregation of 
      AgNPs was proposed for the detection of anti-infective drugs in environmental 
      water. The method enhanced the Raman signal of the targets by 2-7.4 times. The 
      mechanism of aggregation enhancement effect under the low-frequency oscillation 
      procedure which significantly enhanced the SERS signal of targets molecular on 
      the aggregated AgNPs was revealed by UV-vis and ICP-MS methods. Three drugs of 
      cefazolin sodium, pefloxacin, and chloroquine phosphate were determined. The 
      detect limits were 3.97 x 10(-9) mol/L, 2.42 x 10(-10) mol/L, and 
      7.34 x 10(-9) mol/L for cefazolin sodium, pefloxacin, and chloroquine phosphate, 
      respectively. The quantitative relationships were obtained in a wide linear range 
      of 4-5 orders as well as good accuracy and stability with the recoveries of 
      84.0%-97.1% and the relative standard deviations (RSDs) less than 4.6% for spiked 
      in actual water samples. This method also had excellent repeatability and 
      stability, which have potential application for rapid detection of trace 
      pollutants in water environment.
