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 ). WebTo overcome this problem, optical tweezers of today rely on just one beam. The idea is a simple extension of the scheme described above, and involves creating a strong intensity gradient along the direction of the direction of the beam as well (i.e. along the x axis in Figure 1). Ashkin again, in 1986, was the first to create this, grass cutter tractor attachment
