Laser manipulation refers to the use of focused laser beams to control and move small particles or materials. This technique is often employed in scientific research and industrial applications, allowing for precise positioning without physical contact. By adjusting the intensity and direction of the laser, researchers can manipulate objects at the microscopic level. One common application of laser manipulation is in the field of optical tweezers, which use laser light to trap and move tiny biological samples, such as cells or DNA. This technology has advanced our understanding of cellular processes and has potential uses in medical diagnostics and treatment.
