MOESM1 of Magnetic Assembly Route to Construct Reproducible and Recyclable SERS Substrate

Additional file 1: Figure S1. The Fe3O4@SiO2@TiO2 composite microspheres synthesized without using ultrasonic. Figure S2. A calibration curve where the logarithmic intensity measured at 1363 cm-1 peak is plotted versus the logarithmic concentration of R6G. Error bars are standard deviations calculated from 20 independent measurements. Figure S3.
