MIT today announced that a group of scientists has developed nanotechnology that can be placed inside living cells to determine whether chemotherapy drugs are reaching their targets or attacking healthy cells.
The sensors, which can detect chemotherapy drugs as well as toxins and free radicals, are carbon nanotubes that scientists have wrapped in DNA so they can be safely injected into living tissue, according to a release from the university.
"We've made a sensor that can be placed in living cells, healthy or malignant, and actually detect several different classes of molecules that damage DNA," said Michael Strano, an associate professor of chemical engineering at MIT, in a statement.
Last summer, the university used nanotechnology to significantly shrink computer chips, making them cheaper and more powerful. The university said the process would enable the creation of 25-nanometer chips.
