Retrieved from https://hdl.handle.net/1911/80181.https://hdl.handle.net/1911/80181Compositions and methods related to carbon nanotubes are provided. More particularly, imaging agents comprising carbon nanotubes internally loaded with a contrast agent and associated methods are provided. One example of a method may involve a method for imaging comprising: providing an imaging agent comprising a carbon nanotube loaded with contrast agent; introducing the imaging agent into a cell; and imaging the cell to detect the presence of the imaging agent.30 ppengUtility patentUS8986942B2
