Figure 2.

Microscopy images (two leftmost columns) of fivefold-diluted MBs without and with continuous- and pulsed-laser irradiation at 60, 120, and 180 s. The controls labeled as before and after refer to the original (fivefold-diluted) MBs and the MBs remaining on the slide after 180 s in the absence of laser irradiation. The microscopy images in the two rightmost columns are the images of the corresponding leftmost columns converted into grayscale images.
