Nanotube-grabbing "Finger" (IMAGE) Binghamton University Caption Binghamton University nanoscientist, Changhong Ke, relies on unique instrumentation to conduct his nanotube experiments, including a special tool he installed in his laboratory on an advanced electron microscope. This “finger” has a sharp tip that allows him to grab one nanotube at a time and move it precisely.
