When It Comes to Drug Delivery, Size Matters

(PhysOrg.com) -- One of the great promises of nanotechnologies lies in its ability to create drug-containing nanoparticles decorated with targeting molecules that recognize and bind to cancer cells, providing drug delivery only at the site of the targeted cells. Such site-specific drug delivery would not only boost the cancer-killing activity of a drug payload but also reduce potential side effects by greatly restricting or even eliminating the amount of drug reaching healthy tissue.
