Rows of tiny nano test tubes rest on a mesh in this electron microscope photo, shot in October of last year and colorized for added clarity. Seeking to deliver drugs within the body, University of Florida scientists have found a way to “cork” the tubes. The goal is to develop the ability to fill the teeny tubes with drugs and inject them into the body, where they will seek diseased or cancerous cells, uncork and spill their therapeutic contents in the right place.
