Fig 1: (A) Physical image of SERS integrated microarray chip. (B) Average serum SERS spectra of 30 healthy subjects, 30 patients with colorectal pre-cancer and 30 CRC patients. (C) Histogram of SERS intensity corresponding to the characteristic peaks at 1073 cm−1 (hnRNP A1) and 1330 cm−1 (S100P).
Fig 2: (A) SERS spectra of different concentrations of hnRNP A1 and S100P (hnRNP A1: S100P=1:1) in serum. (B) Calibration curve of the logarithmic correlation between the intensity of the characteristic peak at 1073 cm−1 and the concentration of hnRNP A1. (C) Calibration curve of the characteristic peak intensity at 1330 cm−1 related to the logarithm of S100P concentration.
