Reduction of Background Fluorescence from Impurities in Protein Samples for Raman Spectroscopy

Figure 4

Photobleaching of 80 μl of BSA sample in a static cuvette at 500 mW (black square) and 250 mW (red circle) laser power and 500 μl of BSA sample recirculated in a microfluidic device at 500 mW (blue triangle) and 250 mW (green triangle) laser power. The intensities were expressed relative to the initial value as in Figure 3.
