How do optical tweezers work

WebDec 15, 2024 · In their simplest form, optical tweezers consist of a well-shaped optical field that an atom can sit in, like an egg in an egg cup. Since then, optical tweezers have developed into sensitive instruments that can pick up atoms, move them around and even hold them in giant lattices consisting of hundreds of atoms, like eggs in a giant egg box. WebIn a recent study of Rad51, a protein involved in the repair of damaged DNA in humans, investigators employed optical tweezers to manipulate the DNA molecule while directly visualizing the DNA-bound Rad51 enzymes labeled with a fluorescent dye.
