Researchers have developed a new way to control the delivery of drugs to the body using nanoparticles and a weak magnetic field. The inventors, at the University of Georgia in Athens, GA tested their system with a chemotherapy drug, and published the results today in the journal Nature Catalysis.
Patients undergoing treatments for cancer and other diseases often must take drugs that affect the whole body, when they really only need the medicine in a small area. Chemotherapy drugs typically “act on all cells, killing cancer cells and also healthy cells,” says Sergiy Minko, a professor at the University of Georgia and an author of the report. As a result, “a big number of patients die because of complications” from the drugs, he says.
