'Paintable' chemotherapy shrinks skin tumors in mice

Skin acts as the first line of defense against pathogens and other harmful material from outside the body. Yet this barrier also excludes some beneficial drugs that could treat skin diseases. Now, researchers have taken the first steps in developing a chemotherapy for melanoma that can be 'painted' directly on the skin, rather than injected or taken orally. They report their results in ACS Nano.
