Abstract
A nanoscale motion detector attaches a gold nanorod () to the rotating arm () of a molecular structure () to cause the nanoparticle to rotate. The molecular structure is an F1-ATPase enzyme. The gold nanorod is exposed to a light source. The long axis of the gold nanorod scatters red light when the nanorod is in a first position. The short axis of the gold nanorod scatters green light when the nanorod is in a second position. A polarizing filter filters the red and green light to detect the rotational motion by observing alternating red and green lights. A detection DNA stand () is coupled between the gold nanorod and the molecular structure. The detection DNA strand hybridizes with a target DNA strand () if the target DNA strand matches the detection DNA strand to form a structural link between the molecular structure and gold nanorod.
