Optical Tweezers are a scientific tool used to trap and manipulate microscopic particles (ranging from nanometers to micrometers), atoms, and even biological molecules (such as DNA and proteins) without physical contact, using one or more highly focused laser beams. Developed in 1986 by Arthur Ashkin at Bell Laboratories, this technique has become particularly significant in fields such as biophysics, nanotechnology, and colloid science. Arthur Ashkin was awarded the Nobel Prize in Physics in 20
