Fig. 4. Calculation of Raman band intensities and intensity ratios pertaining to different biomolecules in liver and serum. Marker bands were chosen for each of the biomolecules; (A) DNA (784 cm−1), proteins and lipids (1003, 1451 and 1660 cm−1). (B) Ratiometric analysis of two Raman bands – 830 and 854 cm−1. Each circle in the figure represents an individual mouse. Spectra obtained from a total of 4 mice were used for enumeration. Statistical analysis was performed using Mann–Whitney test where * indicates p < 0.05.
