Figure 3: OCT B-scan images of (a) water without NPs, (b) nanorods in water, (c) nanospheres in water, (d) diluted B-GNPs in water, (e) B-GNPs in water, and (f) average A-scan profiles of the water samples. Water without NPs is represented by the black continuous line, nanorods in water by the light gray continuous line, nanospheres in water by , diluted B-GNPs by , and B-GNPs by the gray continuous line.
