From: Ultrasensitive and rapid count of Escherichia coli using magnetic nanoparticle probe under dark-field microscope

Samples Colony counting method
(CFU of 10 μL of sample)

Rice 126 ± 14 112 ± 8
  1. Statistical analysis: The experimental counting results are reported as means ± SE of triplicate independent experiments. Ten fields of view were counted for each sample. Data were analyzed using the SPSS (Statistical Package for the Social Sciences) software (Version 13.0; SPSS, Inc., Chicago, IL)
