Chemotherapy would be a much better option for treating cancer if the medicine could go directly into cancer cells without effecting the delicate blood vessels and healthy cells that surround them. Researchers from the University of Illinois may have found a way to do just that. What the researchers do is take “nanobubbles” of the chemo drug and inject it directly into the cells during critical cell formation. Then, through the use of an ultrasound, the “nanobubbles” are popped and released, killing the cancer cells while sparing the healthy ones. The first tests of the treatment have been a success and the hope is that it can re-purpose chemotherapy drugs to treat difficult forms of cancer better when alternative treatments fall short.
