Fazal FM, Block SM. Optical tweezers study life under tension. Nat Photon. 2011;5(6):318–21.
Abstract: Optical tweezers have become one of the primary weapons in the arsenal of biophysicists, and have revolutionized the new field of single-molecule biophysics. Today's techniques allow high-resolution experiments on biological macromolecules that were mere pipe dreams only a decade ago.
