The influences of induced laser power and reaction time on the properties of tapered fiber surface enhanced Raman scattering (SERS) probes by the laser induced chemical deposition method (LICDM) are studied in experiments. Under an optimized experimental conditions as 90 mW induced laser power and 50 min reaction time, the prepared taper fiber SERS probes possess the highest sensitivity, when detecting a low concentration as 1.0 × 10- 7 mol/L of methyl parathion (MP) solution with a portable Raman spectrometer. Moreover, the prepared probes with LICDM show good repeatability for SERS detections, which may have potentials on rapid and field detection of pesticide residues.
