Optical manipulation is a research area that focuses on using light to manipulate and control small particles or objects. This technique relies on the use of focused laser beams to exert forces on particles, such as trapping them in place or moving them in a controlled manner. Optical manipulation has a wide range of applications in fields such as biophysics, nanotechnology, and materials science, and has led to advancements in areas such as optical tweezers, optical stretchers, and holographic optical traps. By harnessing the power of light, researchers are able to manipulate objects at the microscopic and even nanoscale, opening up new possibilities for studying and manipulating matter at the smallest scales.
