Technology Review (MIT) --Living cells wearing microscopic "backpacks"--nanostructured polymer patches loaded with chemical cargo--might one day be able to ferry drugs or imaging agents to diseased tissue. MIT researchers say that they have successfully constructed such backpacks, filled them with magnetic particles, and tethered them to the surfaces of immune cells without disrupting the cells' ability to interact with their environment. The work is described in a recent issue of Nano Letters.
