A good deal of the field of nanomedicine is focused on delivering drugs to specific sites within the body, such as specific organs or cancer tumors. While many nanomedicines have well developed targeting mechanisms, they often are best delivered a small amount at a time.

Yet, continuous slow-release of nanomedicines has typically required the use of polymer matrix implants that don’t degrade very gracefully.
Now researchers at Northwestern University have developed an unusual new liquid material that, after being injected, assembles into a gel containing drug nanocarriers that can then release themselves at a pre-defined rate. Since the material breaks down into the drug vesicles, nothing remains after all of the medicine is delivered.
