WebAmong the most popular single-molecule manipulation techniques are AFM, and optical and magnetic tweezers, which we discuss in more detail below. Atomic force microscopy ( AFM, figure 3 d ). AFM ( Binnig et al. 1986) is part of the family of scanning probe microscopies, the first of which was scanning tunnelling microscopy ( Binnig & Rohrer 1982 ). Webfrom single-molecule biophysics to nonequilibrium thermal physics. For example, the force generated by kinesin (2), dynein (3), and myosin (4) have been measured in single-molecule biophysics experiments, where typically a single molecular motor is attached to a bead (handle), which is manipulated by the trap. In physics, OTs have been applied
