Killing tumor cells while sparing their normal counterparts is a central challenge of cancer chemotherapy. If scientists could put a “homing beacon” in tumors, they could attract these medicines and reduce side effects caused by the drugs acting on healthy cells. Now, researchers have made a hydrogel that, when injected near tumors in mice, recruits drugs to shrink the tumor with fewer side effects. They report their results in ACS Central Science.
