Laser trapping is a technique that uses focused laser beams to hold and manipulate small particles, such as atoms or molecules, without physical contact. The laser light creates a force that can trap these particles in a specific location, allowing scientists to study their properties and behaviors in detail. This method is widely used in fields like physics, chemistry, and biotechnology. One common application of laser trapping is in optical tweezers, which can pick up and move tiny biological samples, such as cells or DNA. By adjusting the intensity and position of the laser beams, researchers can control the movement of these particles with high precision, enabling groundbreaking experiments and discoveries in various scientific disciplines.
