  Nanocages may help safe delivery of drugs

NEW BRUNSWICK, N.J. (UPI via COMTEX) -- Tiny chemical cages created by researchers at Rutgers University may help deliver drugs to specific organs or tissues without causing harm elsewhere.

Researchers said the cage-like molecules -- only 3.2 billionths of a meter wide -- might also make pesticides less hazardous to handle, filter toxic substances from wastewater and regulate the pace of reactions in chemical production.

"While the concept of chemical cages is not new, we've created new components and advanced the assembly process to increase the chance that they'll become practical," said Ralf Warmuth, associate professor of chemistry and chemical biology at Rutgers and the study's lead researcher. "We've shown a way to securely link molecules together in a cage using an efficient, one-step process."

The study is to be detailed in an upcoming issue of the chemistry journal Angewandte Chemie International Edition and is now available at the journal's Web site.
