Exciting discoveries are often followed by even more exciting applications. One prominent example is the invention of the laser and its myriads of applications in nearly all fields of natural sciences. As was pointed out recently, on the occasion of the lasers’ 50th anniversary, fifteen Nobel Prizes alone were awarded for work dependent on lasers [1]. One particularly useful laser application was the invention of optical traps for small particles, commonly known as ‘optical tweezers’. This discovery was one of those happy accidents that open up new fields of research. Optical trapping as a technique for holding and manipulating micron-sized particles started in 1970 [2], less than ten years after the development of CW lasers [3]. Now, some 40 years later, I am glad to see that this has led to a number of discoveries that resulted in two Nobel Prizes, namely in the physical sciences for the cooling and trapping of atoms by lasers in 1997 and for Bose-Einstein Condensation of atoms in 2001, and also laid the origins of the field of laser trapping in biology. The chronology of the subsequent main discoveries and developments in that field are optical levitation in 1971 [4], an atom cooling suggestion in 1975 [5], optical tweezers in 1978 [6], demonstration of optical molasses in 1985 [7], the first atom trap in 1986 [8], optical trapping and manipulation of viruses and bacteria in 1987 [9], infrared tweezer traps in 1987 [10], internal cell manipulation in 1989 [11], properties of single motor molecules in 1990 [12, 13], basic pair stepping by RNA polymerase in 2005 [14], and DNA sequencing using tweezers in 2006 [15].
