Using injectable self-assembled nanomaterials for sustained delivery of drugs
(PHYSorg.com Nanotechnology)

Because they can be programmed to travel the body and selectively target cancer and other sites of disease, nanometer-scale vehicles called nanocarriers can deliver higher concentrations of drugs to bombard specific areas of the body while minimizing systemic side effects. Nanocarriers can also deliver drugs and diagnostic agents that are typically not soluble in water or blood as well as significantly decrease the effective dosage.
