Figure 8: A quantitative comparison of the contrast measured for ten similar-sized (450–750 nm) SOD1 aggregates.
From: Computational On-Chip Imaging of Nanoparticles and Biomolecules using Ultraviolet Light

The inset shows that the absorption of the SOD1 protein is significantly higher at 266 nm compared to the visible region, explaining the significantly higher contrast in the corresponding images from the UV on-chip microscopy platform. The P values were P < 0.1 for *, P < 0.01 for **, P < 0.001 for *** and P < 0.0001 for ****.
