        How Do Doctors Target Diseased Cells?

        Student animator Steven Handy, from Western Carolina University, was able to show how nanotechnology is allowing doctors to protect healthy cells while attacking tumors with chemotherapy. Nanocarriers allow doctors to deliver higher levels of toxic drugs to cancer cells while reducing side effects in patients, like hair loss, because the drugs don’t start working right away on all cells. Instead, the drugs circulate in the body tied up in nanoparticles which slowly release their deadly payload after enough time has passed for the nanocarriers to accumulate in a tumor.
