Nano-Encapsulated Arsenic May Help Fight Aggressive Form of Breast Cancer

Jul 17, 2010

Northwestern University research team testing nano-drug to discover its maximum effectiveness

The type of breast cancer that the group is targeting affects mostly young women. The Northwestern research team discovered that the drug arsenic trioxide, when encapsulated into a nanobin before injection, can effectively reduced breast tumors in mice. Non-encapsulated arsenic had no effect on the tumors. The arsenic-encased nanobin is able to reach the inside of the tumor cells effectively, whereas non-encapsulated arsenic are excreted too quickly and prove to be ineffective.
