WebAug 22, 2024 · Normalised PCA analysis was performed on the 2nd derivative in the 950–1200 cm −1 region of the FT-IR spectra of the samples , and results in a model with the first two PCs explain 98% of variation in the spectra (PC1 = 87%, PC2 = 7%, PC3 = 4%). Examination of the PCA score plot of the first two coordinates shows that it is not … WebSR-FTIR-SM enabled the detection of PLGA NPs at single-cell level, allowing polymer detection inside the biological matrix by the characteristic band in the 1,700–2,000 cm -1 region. The precise PLGA IR-signature (1,750 cm -1 centered pick) also was clearly evident within an area of high amide density. SR-XRF microscopy performed on the same ... how are you feeling中文
