Device for detecting force to e.g. test performance of DNA-driven micro-motor devices, has detector detecting cooperation of fluorophore with acceptor so as to determine indicator for relative position of two lever-shaped elements

摘要

The device has a fluorophore (20) arranged at a lever-shaped element (3), and an acceptor (21) arranged at another lever-shaped element (4). A detector detects cooperation of the fluorophore with the acceptor so as to determine an indicator for a relative position of the two lever-shaped elements. The lever-shaped elements consist of double-stranded DNA (2). A spring is arranged between the two lever-shaped elements. The former lever-shaped element is formed as a beam balance, and the latter lever-shaped element is formed as a counter bearing for the former element.
