Optical Manipulation
- Focus issue:
- June 2011 Volume 5 No 6 pp315-378
Since their invention 25 years ago, optical tweezers have become the method of choice for physical, chemical and biological experiments that require access to nanometre-scale distances and piconewton-scale forces. The June 2011 issue of Nature Photonics has a special focus on optical manipulation that describes how beam shaping, the orbital angular momentum of laser light, nano-optics and optoelectronics could help advance the field, as well as detailing the impact of optical manipulation in single-molecule biophysics.

Interview with Arthur Ashkin
doi:10.1038/nphoton.2011.101
Since the first discovery of optical gradient and scattering forces in 1970, optical tweezers have helped unveil many mysteries and given deeper insights in many areas of science. Arthur Ashkin, the father of optical tweezers, recalls some 'eureka' moments and shares his viewpoint of the field with Nature Photonics.
