Laser Scissors and Tweezers to Study Chromosomes: A Review
Frontiers in Bioengineering and Biotechnology, 2020 Starting in 1969 laser scissors have been used to study and manipulate chromosomes in mitotic animal cells. Key studies demonstrated that using the “hot spot” in the center of a focused Gaussian laser beam it was possible to delete the ribosomal genes ...

Interferometric Optical Tweezers [PDF]
Optics and Photonics News, 1996 Abstract We report the first experimental demonstration of an optical trap that uses interference fringes for the trapping and micro-manipulation of microscopic objects. The finges can be generated either by two-beam interference or by projecting a reduced image of a Ronchi ruling on the sample plane.
