2. Fig. 1
Top – comparison of a Raman spectrum of dried blood obtained under high power (red) and low power (blue). Bottom – the normalize peak intensity of 1250cm−1 of spectra under various laser power settings (20× objective) and under continuous exposure for three hours (50× objective) with 10% laser power.
