PCA plots to discriminate the 15 chemicals using the NPs-coated MSS. (Top left, top right, and bottom left) The 2D plot with the two principal components. (Bottom right) The 3D plot drawn based on the three principal components. The PCA shown here was performed utilizing four parameters extracted from the last three measured responses shown in Figure S2. The details on the extraction procedure are explained later.
