Nanotechnology is being applied across the continuum of cancer research from devices for monitoring, detection, and cancer imaging to multifunctional nanotherapeutics and post-therapy monitoring tools. The following images, submitted by Alliance members, provide a compelling visual of nanotechnology at work. These images are available to members of the media, researchers, and students to broaden understanding of the application of nanotechnology to cancer research and care. Please note that some images have been enhanced for use in the Image Library by Kathleen Cook, who is with the Nanomaterials for Cancer Diagnostics and Therapeutics CCNE at Northwestern University
