Drs. Jen Adair (left) and Reza Shahbazi examine a test batch of gold nanoparticles at their lab at Fred Hutch. The solution is red because when gold ions clump together to form nanoparticles, electrons on the surface start oscillating and reflecting the light in different wavelengths. Then when light strikes the gold particles, electrons reflect the light differently.
