Raman spectroscopy analysis of ASC-CM samples. (a) Average Raman spectra obtained with 532 nm laser line on air-dried drops of ASC-CM samples. Gray shaded areas represent ±1 standard deviation. (b) Scatter plot of the PC1 and PC2 scores obtained for the 3 considered samples after multivariate statistical analysis (PCA). Ellipses represent the 95% confidence intervals calculated for each sample.
