Scientists in Israel have come up with a way to target cancer without damaging healthy cells. Two researchers at Tel Aviv University developed a nano-vehicle that carries tiny particles of chemotherapy drugs through the body. The drugs are released when the nano-vehicle comes into direct contact with cancer cells. Dr. Dan Peer of Tel Aviv University's Department of Cell Research and Immunology and the Center for Nano Science and Nano Technology and Professor Rimona Margalit of the Department of Biochemistry and Molecular Biology invented the tumor-targeting device. "The vehicle is very similar to a cluster bomb," explains Peer. A sugar...
