Photoacoustic Image of a Melanoma (VIDEO)

Washington University in St. Louis

Caption

With the help of nanoparticles, that are engineered to absorb light strongly, and to bind to proteins on cancerous cells, a melanoma is revealed in stunning clarity. To capture the overlaying blood vessels, the imaging system is then tuned to a different wavelength that is strongly absorbed by hemoglobin.
