Measurement of the toxic effects of chemical compounds on different types of cells is essential to the development of cancer drugs that are intended to kill their target cells. Cell survival analysis is also an important task in areas such as environmental regulation to test industrial and agricultural chemicals for potentially harmful effects on healthy cells. MIT biological engineers have …
